A dynamical model of h2 fuel cell stack with water balance is developed in this paper for studying steady and dynamical performances of proton exchange membrane ( pem ) fuel cell stacks 摘要提出和建立了包含水平衡的氫燃料電池堆的動(dòng)態(tài)模型,用于研究質(zhì)子交換膜( pem )燃料電池堆的靜、動(dòng)態(tài)性能。
A mathematical model for the anode of a direct methanol fuel cell ( dmfc ) considering the mass transport in the whole anode compartment and the proton exchange membrane ( pem ) , together with the kinetic and ohmic resistance effects through the catalyst layer is developed . the influences of key parameters on methanol crossover and anode performance are investigated 對(duì)于dmfc的陽(yáng)極,本文描述了甲醇和水在陽(yáng)極及質(zhì)子交換膜( pem )中的傳遞過(guò)程、反應(yīng)動(dòng)力學(xué)和歐姆阻抗效應(yīng),建立陽(yáng)極和pem的數(shù)學(xué)模型,并探討對(duì)甲醇擴(kuò)散和陽(yáng)極性能影響的主要因素。
