Any other fuel cell pros in the community?

OK - How about some basics on the Etn, Er and the various polarizations WRT fuel cells? Thank you,

Hi All in the community! Any ideas on the elements of the fuel cell polarization curve? Thank you,

Any idea on Fuel cells from the community on this one, Thank you.

So we would use the hydrogen (Made from steam reforming via natural gas) to make the fuel cells then? Thank you-

Thank you both very much- Any ideas on if given a 50-meter tower, at what wind power 'class' and at what 'power level' will wind power be considered economical (in or about the yr 2005)? Best wishes,

Hi all, one last question for today - Given steam reforming of natural gas to generate hydrogen, what is the major difficulty with it with respect to most fuel cells? Thank you,

Hi, Why is height of a wind generators tower so important? Given a 50-meter tower, at what wind 'power class' and at what 'power level' will wind power be considered economical (circa 2005)?

Hi, Given that the band-gap of a silicon PV cell is 1.1 eV, what is the maximum wavelength of solar energy (minimum frequency) required forming an electron-hole pair (EHP)?

Can anyone help me explain the elements of the fuel cell polarization curve. Please be sure to include Etn, Er, and the various polarizations. I am interested by the use of thermodynamics as well... Thank you-
