[TRNSYS-users] fuel cells/electrolyser

[George Kyriakarakos]

Dear all,
The detailed simulation of electrochemical components such as fuel cells and electrolysers needs very detailed parameters, some of which aren't even provided by the companies themselves. I have been trying to model a small system (fuel cell about 1 kW and electrolyser tops 5 kW) and I haven't been able to find the parameters of any commercial products. Luckily I found a publication concerning the evaluation of a fuel cell by Ballard (model Nexa) and I managed to get all the parameters from there, but so far I have been unable to find parameters for a relatively small electrolyser. Has anyone got any data and wants to share them? In order to actually do some simulations I have built a new type which simply takes as input the provided power, uses efficiency of the electrolyser as a parameter and calculates the hydrogen output, but that's not enough.
Thank you in advance,

George Kyriakarakos

PS. The publication I mentioned above is "Uniformity analysis at MEA and stack Levels for a Nexa PEM fuel cell system" by Wenhua H. Zhu, Robert U. Payne, Donald R. Cahela, Bruce J. Tatarchuk, Journal of Power Sources 128 (2004) 231-238
