Mobile Power

Proton Exchange Membrane Fuel Cells (PEMFCs) are being considered as a potential alternative energy conversion device for mobile power applications. Since the electrolyte of a PEM fuel cell can function at low temperatures (typically at 80 °C), PEMFCs are unique from the other commercially viable types of fuel cells. Moreover, the electrolyte membrane and other cell components can be manufactured very thin, allowing for high power production to be achieved within a small volume of space. Thus, the combination of small size and fast start-up makes PEMFCs an excellent candidate for use in mobile power applications, such as laptop computers, cell phones, and automobiles. 

Chapter six considers the impact of fuel cells on power generation. One concept is to use hydrogen cars as mobile power sources. Other topics include the benefits of fuel cells, coal gasification, solar, wind and nuclear power. 

Fuel cell vehicles could provide extra value when they are in use, by acting as these mobile power sources. Most cars are used for 1 or 2 hours of the day. When they are not used, they are often parked where electricity is needed—offices, stores, homes or factories. If all cars were fuel cell pow-...

R D on Mobile Fuel Cell. This project focuses on developing fuel cell technologies (typically DMFC) to generate electricity for mobile eguipment such as mobile phones, electronic terminals, and other mobile power supplies. The project covers R D on components, manufacturing system and evaluation. The 2003 budget allocation is 2.2 billion.

Hydrogen fuel cell cars are unlikely to achieve significant market penetration in this country by 2030. As discussed in the previous chapter, the infrastructure costs alone are likely to run into the hundreds of billions of dollars. Is there a way to jump-start the transition Could fuel cell cars really do double duty as mobile power plants, providing electricity to our homes and offices, as energy experts such as Amory Lovins have suggested These are the questions I examine in this chapter. 

The correspondence of the genetic hazards frame with the symbols and interests of the nascent environmental movement is an important part of the explanation for the frame s resonance and subsequent success at mobilizing a critical mass of concerned scientists, administrators, and policy makers. But as we have just seen, the frame had its weak spots, particularly with respect to the authority of some of its more central empirical claims. The mobilizing power of environmental symbolism does not in itself sufficiently explain the ideological persuasiveness of the genetic hazards frame, particularly with respect to those potential adherents who may have mattered most other research geneticists. 

One of the more important fuel cells is the solid oxide fuel cell Solid oxide fuel cell (SOFC), since they offer a realistic opportunity for use in electric utility operations. A schematic of a fuel cell is shown in Figure 38. These can be developed in stacks having 5-10 kW capacity that would be suitable for both stationary and mobile power units. 

Nickel enters the atmosphere from natural sources (e.g., volcanic emissions and windblown dusts produced by weathering of rocks and soils), from combustion of fossil fuels by stationary and mobile power sources, from the emissions of nickel... 

The new application of hydrogen as a raw material for fuel cells for mobile power sources (PEM fuel cells) requires that the anode inlet gas have a CO concentration lower than 10-20 ppm. Otherwise, the anode is poisoned and the cell efficiency abruptly drops. 

For stationary fuel-cell-based power plants, the most important parameter is the energy conversion efficiency, inasmuch as this will define the fuel consumption per unit of electric power generated. For portable and other mobile power plants, the most important parameters are the power density and the energy density, inasmuch as they reflect the mass and volume of the mobile plant.
