As the world’s energy landscape undergoes transformation and the goals of “carbon peaking” and “carbon neutrality” are proposed, hydrogen energy, with the highest mass energy density and zero carbon emissions, has garnered increasing attention. Proton exchange membrane fuel cells (PEMFCs) are currently a highly promising hydrogen energy utilization technology due to their low operating temperature,

Electrode reactions refer to the chemical reactions that occur at the electrodes where electrons are either lost or gained. The reaction where electrons are lost is called the anode reaction, and the electrode where this reaction occurs is called the anode. The reaction where electrons are gained is called the cathode reaction, and the electrode
