ABSTRACT
The main objective of this study is to design and fabricate a PEM fuel cell stack with open cathodes, and to perform a serial of tests on this stack. By means of this work, the effects of operating conditions on the performance of a fuel cell stack were investigated. The results of this study show that the performance of a fuel cell stack depends on its operating conditions; especially, the mass flow rate of air flowing through the cathodes is the key parameter. The performance of a fuel cell stack can be raised by supplying ample air to the cathode, but this performance raise is limited to a certain extent. Increasing the air flow rate further, the fuel cell will carry more parasitic load and gain no more in performance. Knowing the optimal air flow rate under various stack output, together with the scheme of flow rate control, will be a great benefit to the development of fuel cell system.
Keywords : PEM Fuel Cell, Performance test, MEA.
