No kidding! I wrote most of it, so it's hard for me to do it. Someone please narrow it down so it looks like a more succint and structured encyclopedia entry, instead of a long winded free flowing opinion/argument.
I did some cleaning up. I'm not sure how relevant the whole efficiency discussion is. All the relevant material here could probably be folded into Fuel cell. --Tysto03:10, 6 March 2006 (UTC)[reply]
preposed renameing to Polymer exchange membrane fuel cell
this fuel cell process is actually called Polymer exchange membrane fuel cell (PEMFC) [1]
also info should be put up about this is the desired technology for fuel cell cars running on pure hydrogen.
from the info I've found efficiency are up to 80-percent efficient on the fuel cell its self. That means 2H2 + O2 => 2H2O reaction is up to 80% efficient at generating electricity from the reaction.
