本文提出了一种从燃料电池电压电流曲线估计阴极和阳极电荷转移系数的新方法。与传统方法相比，新技术允许从电压电流曲线的积分特性同时估计阳极和阴极电荷转移系数。算例说明了从PEMFC极化曲线估计参数的方法。该方法与现有的参数估计方法兼容。
This study presents a new technique for estimating cathodic and anodic charge transfer coefficients from fuel cell voltage–current curves. In contrast to conventional approach, the new technique allows estimation of anodic and cathodic charge transfer coefficients simultaneously from integral characteristics of voltage–current curves. Case studies illustrate the parameter estimation from PEMFC polarization curves. The new technique is compatible with available parameter estimation methods.
