Heat with PEM's can be redirected as an agent to warm the membranes, therefore some heat is desirable in the case of PEM's. This one certainly has drawn a lot of interest lately; Baby Ballard?, can't help but love the title, but are they truly competing?

heat schmeet, hood schmood, heat represents a tremendous amount of reusable energy: heaters, air conditioners, any power transducer you like, how does a nuclear power plant work, huh? flux capacitors? just simple steam generation is all.

What about the heat required to reform Metahnol into hydrogen in an external reformer for a PEM?, what about the loss of "potential" energy when reforming methanol? No one cell, product, or solution is going to be 100% efficient. I think it is rather useless to sit here and discuss all these hypotheticals. All this talk about heat makes me think some people want to buy this stock. An ICE engine is hot plain and simple, to say GLE's cell is not a good solution for a auto to me is senseless. If it were a big problem, Delphi would not be working with them, and you could bet the folk at Delphi and whoever else that might be working with GLE wouldn't be considering a SOFC. The same would go for the Auto manufacturers who have announced they are working on a SOFC. I don't know how hot an ICE (internal combustion engine)runs but I have heard people say its hotter inside than a GLE cell, whether this is true or not I do not know. Perhaps someone with a neutral position may want to take a stab at commenting. However to see the topic of heat come up again and then to mention wont the rubber or plastic melt around it is ludicrous. A fuel cell in a car would be encased in a jacket or enclosure im sure and would have insulation / cooling to keep the the outside of it cool, just like a car, just like a Ballard cell. Hey, if NASA can keep the space shuttle from melting when it comes back into orbit I think there must be enough technical know how out there on how to encase/ the cell so that its heat does not effect the balance of the components of a vehicle.

Perhaps you can explain and address this temperature proble in ragards to PEM's and reformers. Wont the reformer melt the rubber and the plastic wpckr? "The main application to date has been for primary power in automotive use. It has the advantage of quick start-up when hydrogen is applied, as well as operating at a very low temperature which allows for easier handling. The disadvantage for the PEM is that it requires very pure hydrogen. When hydrogen is obtained from fuels such as gasoline or natural gas, the reformate gases must be scrubbed to eliminate all CO, sulphur and other contaminants. Although fuel dependent, the reforming process takes place at 700 deg C. Thus, the PEM must wait for the reformer to reach these temperatures before beginning operation. When the PEM is used in stationary applications for a combined heat and power (CHP) application, the overall system efficiency will be lower than high temperature fuel cells as the PEM has only low grade heat available for use.
