well, it takes less time by srgf than by mixed reactant gas feed(mrgf) in gaining the same oriented morphology.
同时,也表明,分离送入反应气体法得到相同定向形貌的时间要比混和送入反应气体法所需的时间要少。
the mass transport of water and reactant gas in gdl, the two-layer structure of gdl and the 「water management」 mechanism of the micro-porous layer, and the research progress in gdl were reviewed.
概述了气体扩散层中水和反应气的传质、gdl的双层结构、微孔层的「水管理」机制以及gdl的研究进展。
reactant gas flow rates needed by proton exchange membrane (pem) fuel cell have important influence on its performance and cost.
