Proton exchange membrane fuel cells (PEMFCs) have a series of advantages such as high efficiency, fast response speed, and zero pollution, which is considered one of the most promising power sources for future transportation, backup power systems, and stationary thermal power generation (Guerrero Moreno et al., in Renewable and Sustainable Energy Reviews, 52: 897–906 (2015)). However, besides cost, degradation is another key issue for the commercialization of PEMFCs. Service life is an important parameter to measure the performance of PEMFCs for automobiles. The U.S. Department of Energy (DOE) has set a target life of PEMFCs of 5000 h by 2020 for passenger cars, 25,000 h for public transport, and 40,000 h for stationary applications.

摘要

Proton exchange membrane fuel cells (PEMFCs) have a series of advantages such as high efficiency, fast response speed, and zero pollution, which is considered one of the most promising power sources for future transportation, backup power systems, and stationary thermal power generation (Guerrero Moreno et al., in Renewable and Sustainable Energy Reviews, 52: 897–906 (2015)). However, besides cost, degradation is another key issue for the commercialization of PEMFCs. Service life is an important parameter to measure the performance of PEMFCs for automobiles. The U.S. Department of Energy (DOE) has set a target life of PEMFCs of 5000 h by 2020 for passenger cars, 25,000 h for public transport, and 40,000 h for stationary applications.
