The Fault Analysis and Diagnosis of Proton Exchange Membrane Fuel Cell Stack
In order to find the reason of the weak performance of a H2/O2 proton exchange membrane fuel cell (PEMFC) stack, a series of fault analysis and diagnosis tests were conducted. According to the test data, the problematic points were focused, and the fault types of the specific single cells were analyzed. It is found that a minimum of three groups of diagnosis tests based on three relatively high load resistances and a voltmeter could judge the working condition of the PEMFC stack and confirm the fault types of its single cells. The method is useful for quick detecting and handling of PEMFC stack in Industrial field and home usage.
