Abstract | The uncertain condition in Proton Exchange Membrane Fuel Cell (PEMFC) affected by many factors either from the design characteristics itself or from the operating conditions. Unstable voltage in PEMFC occurs for every changes load demand and requires time to warm up before it reaches the stable voltage conditioned. An unstable power supply can damage the entire system and even put the life of an operator at risk as well as decreased its life time. This research required to analyses and extracts the PEMFC voltage signal under various stack temperature conditions and changed load demand. Time‐frequency distribution (TFD) is presently used as technique to analyse the PEMFC voltage signal. The parameter of instantaneous direct current (VDC), instantaneous root mean square (VRMS), and instantaneous alternating current (VAC) are extracted and from the spectrogram result. Such relationship between instantaneous VDC, VRMS, and VAC parameter on every load demand at various stack temperature are discussed and summarized. Thus, this parameter estimation is significant to be used in development of system |
