Fuel cell high temperature

H2 production for fuel cell (high temperature solid fuel cell and molten carbonate) is also possible. 

Appendix A shows that for equilibrium fuel cells, high-temperature operation offers no advantage, but indeed a theoretical disadvantage. However, in a practical non-equilibrium set-up, where unused fuel and unconsumed oxygen are features and these have to be combusted in a gas turbine, the high-temperature fuel cell is likely to be at an advantage. Further discussion appears on this point in Chapters 4 and 5, in respect of the SOFC and the MCFC. The PEFC (Chapter 6) must, for...

Fuel cells of this variety sometimes are called high-temperature or mid-temperature polymer electrolyte membrane fuel cells, but is preferable to use the designation given in the section heading, as in their application to high-temperature fuel cells, high-temperature and mid-temperature refer to different temperature ranges.

Fuel cells have been classified into two major categories high-temperature fuel cells and low-temperature fuel cells. High-temperature fuel cell technology is best suited for stationary plant applications, where they can meet the emergency power requirements in case the main power plant generators are shut down for repairs or schedule maintenance. High-temperature fuels cells also can be deployed to power submarines. 

Current collector material and manufacturing engineering are active areas of research and development. Presently, a variety of materials are used for bipolar plates in fuel cell stacks. Specially coated metals, graphite, and doped polymers have been used for low-temperature fuel cells. High-temperature fuel cells have primarily utilized ceramics for this purpose.
