Energy management simulation in a PEM fuel cell system

In this research the simulation of an air independent PEM fuel cell propulsion system was taken into-consideration. The system consisted of a PEM fuel cell stack, metal hydride and liquid oxygen (LOX) tanks, and pre-heaters of oxygen and hydrogen gases which along with other heat exchangers cool the PEM fuel cell stack and use its wasted heat effectively in other sections. In this case study the operation of the whole system, inducing utilizing the wasted heat from the PEMFC have been simulated, and the effects of operating parameters such as PEMFC power, its operating temperature and cooling water mass flow rate were investigated and discussed.
