采用催化剂层(CL)性能模型,通过CL厚度确定电解质含量和催化剂负载的最佳形状。优化的效果很大程度上取决于无因次工作电流密度j ~ 0。对于氢电池来说,在小的约0特性下,阴极优化的效果是边际的,而对于直接甲醇燃料电池来说,在大的约0特性下,阳极的优化使CL性能翻了一番。
A model for catalyst layer (CL) performance is used to determine optimal shapes of electrolyte content and catalyst loading through the CL thickness. The effect of optimization strongly depends on the dimensionless working current density j˜0. At small j˜0characteristic to a hydrogen cell, the effect of cathode optimization is marginal, while at large j˜0typical for a direct methanol fuel cell, optimization of the anode doubles the CL performance.
