The performance testing of a Membrane Electrode Assembly (MEA) with Pt-Co/C catalysts in a Proton Exchange Membrane Fuel Cell (PEMFC) under varying hydrogen gas flow rates has been conducted. The MEA consists of electrodes comprising an anode and a cathode involving Pt/C and Pt-Co/C catalysts. The electrodes were characterized using X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), a…
