Proton exchange membrane fuel cells (PEMFC) are potential alternatives to fossil fuels as energy sources for automotive and stationary applications due to their high energy efficiency, high power density, quick start-up, low operating temperature, continuous operation, modularity, fuel flexibility and low greenhouse gas emissions. Despite these advantages, PEMFCs still face problems of high costs and less than desired durability that have limited their widespread use. These costs are linked to their reliance on platinum (Pt)-based electrocatalysts and the high Pt loading levels required in the cathode catalyst layer to compensate for the slow kinetics of the oxygen reduction reaction (ORR).

质子交换膜燃料电池(PEMFC)具有能量效率高、功率密度高、启动快、工作温度低、连续工作、模块化、燃料灵活性和温室气体排放低等优点，是潜在的化石燃料的汽车和固定能源替代品。尽管有这些优点，质子交换膜燃料电池仍然面临着成本高和耐用性差的问题，这限制了它们的广泛使用。这些成本与它们对铂(铂)基电催化剂的依赖以及阴极催化剂层中需要较高的铂负载量来补偿氧还原反应(ORR)的缓慢动力学有关。
