<< Hi Vance,

Does a fuel cell mount outside? In salt water? Under pressure?
I invisioned it had to be inside in a 1 atm environment. Am I wrong?

Regards,
Ray

crew compartment, high heat is dissipated externally, ultimate heat sink is handy for 
recirc cooling? It's a trick question. Right? Vance

The Perry fuel cells used in the late 60s on Hydro-Lab and the much more current variety built for and used on the PC-14 (prior to its acquisition by the new owners, who stuck with the battery packs) utilized hard cans, like battery pods. The fuel cells were in 1 atm, but not under the seat, so to speak.
