质子交换膜燃料电池水、热、气管理

Water, heat and gas management of proton exchange membrane fuel cell

质子交换膜燃料电池的水、热、气管理对其性能和寿命有非常重要的影响。讨论了水、热、气管理的主要措施和它们对电池性能的影响。分析表明 :对质子交换膜燃料电池物理机制认识的不足 ,是水、热、气管理水平较低的原因。应建立质子交换膜燃料电池的多尺度、多相、多物理场、动态仿真模型 ,进行分析、模拟和优化 。

The water,?heat and gas management of proton exchange membrane fuel cell (PEMFC) played a very important role in its performance and life.The main measures of the water,?heat and gas management and their influence to the PEMFC performance were discussed.The poor management of the water,?heat and gas in PEMFC was due to less understanding of the physical mechanism of PEMFC. A multi-scale, multi-phase, multi-physical, dynamic model should be developed to analyze, simulate and optimize the PEMFC for enhancing its performance.
