I've spent innumerable time over the years looking for commercially available hydrogen / oxygen fuel cells that might actually be usable in one project concept or another. The best I've ever managed to find was a cell stack about the size of a backpack. However its power output was a paltry 1 kW. I have sporadically found references to tests with and without a centrifugal blower. Which showed there was a tangible difference. But which still didn't even approach my power requirements.
Is there a stack available, or is it at least possible to feed a fuel sell stack with high pressure gas's to obtain higher power output? More specifically is the relationship between input pressure linear with the power output of the stack?

... not very useful information ... please describe your requirement ... edit the post and add the info ... do not write a comment $\endgroup$
