Fuel for Fuel Cells

I am not sure what you are talking. Solid acid base fuel cell or solid oxide fuel cell. Solid acid based fuel cell are low temperature fuel cell and release of hydrogen is its interaction with water or acid or other chemical which allows hydrogen release to react with oxygen and produce powder

On the solid oxide fuel cell on the other hand is high temperature operation and can take all type of fuel from methane to diesel (practically any thing which can be burned . System used reformer to produce hydrogen and then catalyst and oxygen carrier to have hydrogen oxygen reaction to make power. This is nickel or platinum based catalyst and operation is generally high temperature from 600 to 1200 oC. They are good as stationery system and also good as personnel power system to charge cell and small mobile devices but is yet little far away from power plant

And, to add a few more questions: What are the feedstocks to a solid acid based fuel cell, and what effect will their use have on the ecology (e.g., scarcity, waste products, energy to pre-process, etc.)

For those who are interested, a google searrch resulted in this concerning SAFC's: http://www.sciencemag.org/content/303/5654/68.abstract

It is SOFC and not SOAC. The search is http://www.google.com/search?client=gmail&rls=gm&q=Sofc You will see the result when you go to the web site

Hey, Guest, read again, It is SAFC (Solid Acid Fuel Cell) as I wrote it. SOFC is Solid Oxide Fuel Cell. They are two different items. Now, if you type "solid acid fuel cell" into Google, you will get a number of hits. You will see, too, that SAFC's are new to the fuel cell research. It would appear, from most of what is apparent from a quick survey of the Google search that the safc is being researched for mobile applications rather than stationary applications. As far as I can determine, it seems that the SOFC with heat reconvery is sstill the better choice for stationary uses, both in the 2kW to 10kW range and the larger, 100,000kW and grearter range. Of course, the research is still pending on the SAFC, having been reported only since 2004 or so. Although the SOFC is coming on the commercial market now, 2011-2012, the SAFC is still worth keeping in mind as we move forward.
