摘要
增湿技术是质子交换膜燃料电池(PEMFC)的关键技术之一。设计了一种阴极面带增湿槽道流场板,增湿槽道中液态水蒸发成气态水透过疏水碳纸向邻近的气体槽道和催化层扩散进行增湿。单电池在电流密度为600mA/cm2工作时,内阻在0.051～0.066Ω·cm2区间波动;表明了采用增湿槽增湿方式达到了良好的增湿效果并实现了电池稳定工作。
Humidifying technology is one of key technologies for proton exchange membrane fuel cell （PEMFC）, One cathode flow field plate with diffuse increased wet channels was designed. Liquid water evaporated gas through carbon paper to adjacent gas channel and catalyst layer. The data of single cell test show that when the density of the electric current is 600 mA/cm^2, the resistance fluctuate is in 0,051-0.066 Ω2·cm^2 ranges, and the method of increased wet channels achieves good humidification effect and realizes cell stable work,
