Lifetime is an important parameter to measure the performance of automotive PEMFCs, and currently it is one of the key limiting factors in their commercialisation . As a fixed power supply, PEMFC can reach a lifetime of 30,000 h, while it can only last 2500–3000 h in automotive applications, which is far from the commercial requirement of 5000 h . The degradation of fuel cell components is the primary cause of the short service time. The durability of each component is influenced by various factors, including material characteristics and stability, operating parameters (temperature, humidity, etc.), operating conditions (start-stop, idling, cold start, load changing, etc.), system integration, and contaminants. In order to improve the lifetime of PEMFC, there has been a focus in recent years on studying its degradation mechanism.
