Main Question or Discussion Point

Hello,

Can you tell me please the mass flow rate of hydrogen and oxygen per unit of area of electrodes in fuel cells? Or if you have information on the mass flow rate of hydrogen and air per volume of fuel cell stack?

I understand this may vary, but I am looking for publications or other sources that have such info, even if it is for specific fuel cells.

Thanks

Of course it would vary with the make and model, but especially with how much power is consumed. You'll need more specifications before that can be answered. But the best answers are likely to come from manufacturers.

Not all fuel cells are alike. For general information, I would start here https://en.wikipedia.org/wiki/Fuel_cell#Types_of_fuel_cells;_design
Then I would follow the links in the reference section of that article for more details.
