碩士 / 國防大學中正理工學院 / 造船工程研究所 / 93 / The air independent propulsion system makes the routine possess the submerge ability for a long time like sneaking the nuclear power definitely warship, The major advantages of AIP collocate proton exchange membrane fuel cell system are：high energy density , low temperature operate , oxygen consumption low and to reduce noise. Then, in this study, the PEMFC is the target of study.
In numerical simulation, adopt CDF-RC software, first under 0.6 V situations to operate the voltage, consider activation polarization, ohm polarization and concentration polarzation three losses, to relative humidity, porosity and aspect ratio to act as the discussion. The parameter effect of aspect ratio is better than relative humidity and porosity.
Secondly, only consider the effect of the activation polarization in operate the density 150 Amp/m2 of the electric current cases, to discussion that such parameter effects as the relative humidity and porosity, its result is relatively close to the ideal battery characteristic curve. Synthesize result the above, CFD-RC in operate software electric current under the density 150 Amp/m2, than operate accuracy its voltage 0.6V high.
