As a key component of proton‐exchange‐membrane fuel cells (PEMFCs), proton‐exchange membranes (PEMs) must continuously withstand very harsh environments during long‐term fuel cell operations. With the coming commercialization of PEMFCs, investigations into the durability and degradation of PEMs are...
