Abstract

This paper uses a 5kW Ballard PEMFC (proton exchange membrane fuel cell) Mark V manufactured by Canadian company as power sources for autonomous underwater vehicles. The PEMFC works with pure H2 and O2 as the reactant gases. Moreover, the effect of the operating temperature and operating pressure on the polarization curve of PEMFC is analyzed in this paper. Since the output voltage of PEMFC can be easily affected by load variations and polarization losses, its output voltage is not stable. Thus, a DC/DC power converter with a voltage mode control is designed to automatically regulate the output voltage of PEMFC in this paper. Based on the output voltage of Ballard PEMFC, the output voltages of 5V, 12V, 24V and 48V DC can be obtained to supply for autonomous underwater vehicles. Additionally, the effects of load change on the voltages and currents at the source and load terminals are investigated in this paper.
