质子交换膜氢燃料电池自增湿膜电极的研究进展

氢燃料电池是一种绿色、高效的新型电池,具有能力转化效率高、低噪音无振动、绿色无污染等优点。质子交换膜氢燃料电池可在常温甚至低温条件下工作,具有广阔的应用前景。然而,质子交换膜全氟磺酸离聚物需要在充足的水作用下才能进行质子的传递,而膜电极本身不能产生水,因此需要将阴极的水逆传递到阳极才能保证膜电极的性能,自增湿质子交换膜可以保持氢燃料电池低湿度条件的电池性能和稳定性。本文综述了自增湿膜电极的研究进展。

Research Progress on Self-humidifying Membrane Electrode of Proton Exchange Membrane Hydrogen Fuel Cell

Hydrogen fuel cell is a new type of green and efficient battery,which has the advantages of high capacity conversion efficiency,low noise,no vibration,and green pollution.Proton exchange membrane hydrogen fuel cells can work at normal or even low temperature,and have broad application prospects.However,the proton exchange membrane perfluorosulfonic acid ionomer requires sufficient water to transfer protons,and the membrane electrode itself cannot produce water.Therefore,the cathode water needs to be reversely transferred to the anode to ensure the performance of the membrane electrode.Self-humidifying proton exchange membranes can maintain the performance and stability of hydrogen fuel cells in low humidity conditions.This article reviews the research progress of self-humidifying membrane electrodes.
