<DIV><FONT face=Arial size=2>Dear all,</FONT></DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2>Thank you in advance,</FONT></DIV>
