If an electrode has large discharge capacity, the opposite electrode on the same bipolar plate is degraded by the reverse current. In this study, discharge capacity of various transition metal-based electrocatalysts was investigated to clarify the determining factors of electrocatalysts on the reverse current and durability. The discharge capacities from 1.5 to 0.5 V vs. RHE (Qdc,0.5) of electrocatalysts are proportional to the surface area in most cases. The proportionality coefficient, corresponding to the specific capacity, is 1.0 C·m–2 for Co3O4 and 2.3 C·m–2 for manganese-based electrocatalysts. 2023-04-20T07:01:27Z 2023-04-20T07:01:27Z 2023 Book https://link.springer.com/article/10.1007/s12678-023-00815-0 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8145 en application/pdf Springer
