For instance, most MEA studies in the literature usually follow the US DoE Degradation protocol for fuel cells and fuel cell components. The protocol consists of 30 000 trapezoidwave cycles in a voltage range similar to that which is expected for an automotive drive cycle (0.6-0.95 V), with a 3 s hold at each potential, at 80 °C, thus simulating close-to-real operational conditions. On the other hand, RDE stability studies typically vary with respect to this protocol.
