Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

I am completely stumped right now (in many different ways). I am a senior in Electrical Engineering and just started an internship this summer. Sadly, they put me in a setting which involves nothing I have studied except the pure math (there is not a volt or ampere that I have seen yet).

I am trying to estimate the heat transfer coeffecient and use this in COMSOL of a hydrogen fuel cell. To be honest I have never seen any of these equations before and am really flustered. They mentioned that the h would be different for each side of the cell.

Supposing the cell is X by Y length, how would one get a ballpark estimate on the h for each side? (One side is assumed to the symmetric center, so no heat flows through here).

Any help is appreciated (as well as any tips or tutorials for COMSOFT).

Thanks,

John
