<p>Optimising the performance of proton exchange membrane water electrolysers (PEMWEs) requires mechanistic insight into electrocatalyst behaviour under device-relevant conditions. Here, we report an operando PEMWE for synchrotron XAS with an incorporated reference electrode, enabling catalyst structure and oxidation state to be correlated directly with anode potential. Electrochemical benchmarking against a conventional PEMWE with identical catalyst-coated membranes shows that representative an...</p>
