Sectors of Applications

Each market needs fuel cells for varying reasons described as follows  

Stationary fuel cells can produce enough electricity and heat to power an entire house or business, which can result in significant savings. These fuel cells may even make enough power to sell some of it back to the grid. Fuel cells can also power residences and businesses where no electricity is available. Sometimes 

2 Fuel Cells Operating and Structural Features of MCFCs and SOFCs 

Many factors are contributing to the fuel cell push in the automotive market. The availability of fossil fuels is limited, and due to this, an inevitable price increase will occur. In addition, legislation is becoming stricter about controlling environmental emissions in many countries all over the world. One of the new pieces of legislation that will help introduce the fuel cell automobile market in the United States is the Californian zero emission vehicle (ZEV) mandate, which requires that a certain number of vehicles be sold annually in California. Fuel cell vehicles also have the ability to be more fuel efficient than vehicles powered by other fuels. This power technology allows a new range of power use in small two-wheeled and four-wheeled vehicles, boats, scooters, unmanned vehicles, and other utility vehicles [30-34],

Although electrostatic separation (static or high intensity) has not been applied widely in solid waste treatment at the industrial level, it is expected to be of wider use in the future in certain sectors of applications. This separation has been successfully applied to separate plastics from paper, plastics from each other, shredded copper wires from their plastic insulation, glass from plastic, nonferrous metals from plastic, or glass, for example. 

Introduction and commercial application Investment opportunities in the exploration and production (E P) sector of oil and gas business are abundant. Despite areas such as the North Sea, Gulf of Mexico and the North Slope in Alaska being mature areas, there are still many new fields under development in those regions, and new areas of business interest are opening up in South America, Africa and South East Asia. Some fields which have a production history of decades are being redeveloped, such as the Pedernales Field in Venezuela. 

However, in various industrial sectors the application of the radioscopic inspection technique is aggravated by a lack of the respective standards, contrary to radiography. This leads to complicated approval bureaucracy by the respective supervisory or certificatiomn authorities. 

To support them, therefore, immense activities are prompted both in pubh c private sectors with increasing importance on NDT. The particular application of radiography using Ir-192 isotopes for industrial production, construction maintenance of industries, power plants, oil and gas pipelines plants, railway, aviation systems, naval structures and vessels, etc is currently in the fore front for its reliabih ly, ease of application record keeping advantages. 

Electronic Applications. Electronic appHcations make up a significant sector of the cesium market. The main appHcations are in vacuum tubes, photoemissive devices, and scintillation counters (see Electronic materials). 

Disk Filters A disk filter is a vacuum filter consisting of a number of vertical disks attached at intervals on a continuously rotating horizontal hollow central shaft (Fig. 18-127). Rotation is by a gear drive. Each disk consists of 10 to 30 sectors of metal, plastic, or wood, ribbed on both sides to support a filter cloth and provide drainage via an outlet nipple into the central shaft. Each sector may be replaced individually. The filter medium is usually a cloth bag slipped over the sectors and sealed to the discharge nipple. For some heavy-duty applications on ores, stainless-steel screens may be used. 

In principle GD-MS is very well suited for analysis of layers, also, and all concepts developed for SNMS (Sect. 3.3) can be used to calculate the concentration-depth profile from the measured intensity-time profile by use of relative or absolute sensitivity factors [3.199]. So far, however, acceptance of this technique is hesitant compared with GD-OES. The main factors limiting wider acceptance are the greater cost of the instrument and the fact that no commercial ion source has yet been optimized for this purpose. The literature therefore contains only preliminary results from analysis of layers obtained with either modified sources of the commercial instrument [3.200, 3.201] or with homebuilt sources coupled to quadrupole [3.199], sector field [3.202], or time-of-flight instruments [3.203]. To summarize, the future success of GD-MS in this field of application strongly depends on the availability of commercial sources with adequate depth resolution comparable with that of GD-OES.

Trade in chemical substances, many of which may be potentially harmful, is of course international, and the application of the products of the chemicals industry is essentially global. Main sectors of use include ... 

The Promochem Group was the first international specialist supplier of certified reference materials (CRMs) and pharmaceutical reference substances used in environmental, medical and trace element analysis. Their experience provides a viewpoint that echoes, reinforces and expands on many of the trends discussed above (Jenks 1997). From the middle of the 1980 s, sales of CRM by Promochem increased between 10 % and 20 % annually, depending on the market sector and application. Since then National and International Metrology Institutes, such as the now privatized U.K. Laboratory of the Government Chemist (LGC), the European and U.S. Pharmacopoeias, the E.U. IRMM and others have recognized that efficient distribution of RMs, backed by available technical support, is as important as production and certification. Thus, they have moved to spread their influence outside their national origins. The Web and e-commerce will continue to grow as major facilitators of better information dissemination and supply of CRMs. 

Specificity is unsurpassed. Traditionally, MS was performed on very large and expensive high-resolution sector instruments operated by experienced specialists. The introduction of low-resolution (1 amu), low-cost, bench-top mass spectrometers in the early 1980s provided analysts with a robust analytical tool with a more universal range of application. Two types of bench-top mass spectrometers have predominated the quadrupole or mass-selective detector (MSD) and the ion-trap detector (ITD). These instruments do not have to be operated by specialists and can be utilized routinely by residue analysts after limited training. The MSD is normally operated in the SIM mode to increase detection sensitivity, whereas the ITD is more suited to operate in the full-scan mode, as little or no increase in sensitivity is gained by using SIM. Both MSDs and ITDs are widely used in many laboratories for pesticide residue analyses, and the preferred choice of instrument can only be made after assessment of the performance for a particular application. 

It goes without saying, that all the aspects pointed out give rise to a great number of applications in industrial and academic sectors 138). In future, the use of specific computer programs 139) will help to reach some of the goals more easily. 

This capacity is applicable in various sectors of the food industry such as bioremediation, beverage processing, ascorbic acid determination, sugar-beet pectin gelation, and baking it also acts as a biosensor.
