The internal humidity of vehicular proton exchange membrane strongly influences the performance of PEMFC, but it cannot be measured directly because of the special closed structure. Generally, the internal humidity is equivalent as the water content of the membrane. This paper studies the problem in humidity measurement. In the base of analysis about PEMFC water content mechanism, and by taking Fuzzy Sets as method, this paper builds a PEMFC humidity status monitor system model, which can monitor the humidity value and evaluate the FC system humidity status. The simulation results show that the model is working properly. |
