摘要:
Recently,polymer electrolyte fuel cell(PEFC)begins to be used in a lot of fields such as automotive industry and power generation etc.Therefore our laboratory developed the simple maintenance equipment which can diagnose a performance degradation of PEFC instantaneously by analyzing transient response at a current interruption.However,because it was not able to diagnose some operating conditions,we determined that it was necessary to improve the diagnostic algorithm.Therefore we developed a new algorithm which sequentially approximates diagnostic parameters by the on-line algorithm of the method of least squares.The adequacy of a new algorithm was verified using a PEFC single cell of 25 cm^2 applied about two Membrane Electrode Assemblies(MEAs)((a)10 mg,(b)7.5 mg)with different amount of platinum.As a result,we judged that this algorithm was able to apply to the new diagnostics because it distinguished the difference of two MEAs in each parameter.
