PEMFC低温起动研究进展

Research progress of cold-start for PEMFC

质子交换膜燃料电池(PEMFC)具有环境友好、效率高和室温可快速起动等优点,被认为是汽车的首选动力源。分别对PEMFC的质子交换膜、催化层、扩散层、低温扫气及其建模的低温研究现状进行了详述,并提出了今后质子交换膜燃料电池低温起动研究的方向和重点。

The proton exchange membrane fuel cells （PEMFCs） are considered as the preferred power source of the automobile due to its many advantages such as environment friendly, high efficient and quick start for room temperature, etc. The subfreezing research status of the proton exchange membrane, the catalyst layer, the diffusion layer, the subfreezing purge and modeling methods of PEMFC were respectively reviewed, and then the research trend and focuses of future cold-start of PEMFC were proposed.
