I understand the principle of electrolysis and how H2O forms O2 and H2, but does the process behave the same under higher pressures? Say up to like 200 psi? Might this require a higher voltage to sustain the same rate of reaction?

Any input is greatly appreciated. I am an electrical engineer and have recently sparked an interest in fuel cell tech.

Edit: I am not sure I put this in the right board. I picked this because I myself happen to be an undergrad, but I guess this question may have fit somewhere else a little better.
