Someone wrote that it would be reduced to $30/kWh. If you read the reference closely, that's not what it actually says. I'll correct this, but I thought I'd note it here too.
I don't know when the above was written, but on a similar note, I was unable to find a point where the US DoE had stated that the cost had dropped to $73/kWe. At the end of April 2009, they were expecting the price to drop to $400/kWe. --Grunkhead (talk) 17:27, 28 June 2009 (UTC)[reply]
perhaps the hydropak can be mentioned. If it was to be refillable, it would be a perfect device —Preceding unsigned comment added by 81.246.171.164 (talk) 09:02, 30 March 2009 (UTC)[reply]
I was wandering if it would be alright to put observations that I have noticed while working on fuel cells myself with the DOE at Stark State College of Technology? I have noticed that in some of our fuel cells that we are seeing an increased amount of moisture on the anode side of our fuel cells under test that have a hydrogen source with a purity of 99.99995% purity. I believe that we are seeing O2 crossover from the cathode side of the fuel cell to the anode side at which point it reacts with the hydrogen already present on the anode side to produce H2O. Any input on this matter would be appreciated as I am still fairly new to editing on Wikipedia and can use all the help that I can get. andrew e0 2000 (talk) 3:55, 1 July 2009 (EST)
None of the information in this table is cited, which I would have thought was against Wikipedia policy? I have added a cost for PEMFC cells and mentioned my source the edit summary, but didn't put it in the main table as it would have been the only one. Would someone with the free time like to collect some citable data - or would all the references clutter up the table? Wogone (talk) 11:50, 14 July 2009 (UTC)[reply]
"batteries store electrical energy chemically and hence represent a thermodynamically closed system." This is a bit misleading as when you go to use the battery it is now an open system, unless you include the circuit it powers, in which case the battery and circuit together can be approximated to a closed system. Maybe I'm wrong and or it's not such a big deal but I found it a bit confusing. TFJamMan (talk) 09:58, 4 August 2009 (UTC)[reply]
According to http://www.mwcog.org/uploads/committee-documents/v1ldW1s20060524145809.ppt, efficiency is 40-60% rather than 50% —Preceding unsigned comment added by 81.243.178.120 (talk) 05:59, 14 August 2009 (UTC)[reply]
I vote to change the intro to
A fuel cell is an electrochemical cell that produces electricity from a replenishable fuel tank. The electricity is generated trough the reaction, triggered in the presence of an electrolyte, between the fuel (on the anode side) and an oxidant (on the cathode side). The reactants flow into the cell, and the reaction products flow out of it, while the electrolyte remains within it. Fuel cells can operate virtually continuously as long as the necessary flows are maintained.
Fuel cells are different from conventional electrochemical cell batteries in that they consume reactant from an external source, which must be replenished[1] —Preceding unsigned comment added by 81.245.90.148 (talk) 11:25, 9 October 2009 (UTC)[reply]
