The number of published fuel-cell-related models has increased dramatically in the past few years, as seen in Figure 2. Not only are there more models being published, but they are also increasing in complexity and scope. With the emergence of faster computers, the details of the models are no longer constrained to a lot of simplifying assumptions and analytic expressions. Full, 3-D fuel-cell models and the treatment of such complex phenomena as two-... 

Another important, fuel cell-related invention is to reduce the differential pressure (d/p) between the cathode and anode chambers and thereby reduce not only the thickness of the separation diaphragm, but also the overall size, weight, and cost of the whole RFC unit. This goal is achieved by replacing the presently used pressure difference controllers with much more sensitive ones. 

There are two types of electrochemical interactions with bacteria bactericidal and fuel-cell related. 

Fuel-cell manufacturing costs and the directiy related retail prices are expected to be strongly affected by the established production volumes and the corresponding learning effects. These volumes depend on the rate of fuel-cell commercialisation, which is expected to be determined by their price competitiveness. In this context, the fuel-cell-related industry, the most cmcial leveraging factor for fuel- ced market development, is of major importance, and also represents an indicator of the situation so far and its near-term future potential (Pehnt et al., 2004). 

Fourier transform infrared (FTIR) and in-situ FTIR spectroscopy are among many modern instrumental tools of analytical chemistry well established in fuel-cell-related electrochemistry [1]. In general, FTIR spectroscopy is a valuable tool in the characterization of fuel cell technical electrodes, where the nature of surface groups can be identified, since such electrodes are rather difficult solid surfaces on which to work. FTIR is among the methods less commonly used for the characterization of dispersed catalysts and supports, but as a technique is able to give an idea about the nature of the surface groups on carbon supports and on the structure of adsorbed species on noble metal clusters. 

Being a one-carbon organic molecule, formic acid has also drawn attention as a potential fuel for fuel cell related applications. When considered in acidic media, the oxidation of formic acid proceeds according to the following reaction. 

Very low viscosities can lead to satellite formation and lack of acoustic damping but organic solvents such as methanol with viscosities less than that of water (1 cP) can be jetted. Very high surface tension presents unique challenges, but the solder discussed in Fuel Cell Related Materials Printing has surface tension greater than 400 dynes cm", or roughly six times that of distilled water.

A very detailed fuel cell-related TEM study of CB and CB corrosion can be found in Eiu et al. [15]. Gas adsorption, Hg intrusion porosimetry, and small-angle X-ray scattering (SAXS) provide information on porosity and pore size distribution, each of them having its own advantages and limitations. Methods that can be used to probe the functional groups at the carbon surface are X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption spectroscopy (NEXAES). Table 7.1 gives an overview of characterization techniques applied... 

Another method for measuring mechanical properties on the macroscopic scale uses the relation between mechanical properties and the propagation of acoustic waves [89]. The velocity of sound waves and also the damping thereof can be directly deduced from the elastic and viscous properties. For polymers, ultrasound can be used since the damping of the acoustic waves is decreased at high frequencies. However, this method seems not to have been applied to fuel cell-related membrane materials so far. 

The fundamental problems of fuel cells related to electrocatalysis also need to be addressed for improvement in performance, as highly selective catalysts will provide better electrochemical reactions. 

Due to the ample potential of fuel cell commercialization using non-Pt alkaline membrane fuel cells, studies on anion exchange membranes for this technology are now an emerging field both in terms of research and development. Figure 1 shows the main research locations (both universities and companies) in which alkaline membrane fuel cell-related fields were or still are being developed [1]. More than 90 % of the indicated specific locations (denoted by yellow dots) focus on the development of anion exchange membranes.
