Abstract

This paper simulates the electrical behavior of a Ballard Mark V 35-cell 5 kW PEM (proton exchange membrane) fuel cell with power converters under load changes in order to assess whether it can be used as an energy source to power an autonomous underwater vehicle (AUV). Since the fuel cell produces an unregulated dc output voltage, PWM (pulse width modulated) dc-dc converters are connected to the studied fuel cell for converting the unregulated voltage into 5-, 12-, 24-, 24-48-, 120-and 150-V and supplying to the AUV's loads. The fuel cell model considered in this paper consisted of the double-layer charging effect, gas diffusion in the electrodes and the thermodynamic characteristic. Moreover, dc-dc converters are assumed to operate in continuous-conduction mode with a voltage-mode control compensator. The models of the fuel cell and dc-dc converters have been implemented in a MATLAB/SIMULINK. environment. Results show the output voltages of the Ballard Mark V PEM fuel cell with dc-dc power conversion during a load change are stable.
