在碱性聚合物电解质膜燃料电池（APEMFC）中，由Pd涂覆的Pt丝组成的原位燃料电池参比电极（RE）表现出稳定的电势。结果表明，阳极的过电位和阻抗高于测试的电池中的阴极（即使在低电流下），这是相反的质子交换膜燃料电池（PEMFC）中发现的，它表明，需要谨慎翻译之前的低估PEMFC APEMFC时。工作假设是在阳极（其中水是电生成的）处存在由电解产生的质量传递损失。
An in-situ fuel cell reference electrode (RE) consisting of a Pd-coated Pt wire exhibits stable potentials in alkaline polymer electrolyte membrane fuel cells (APEMFC). Results indicate that the overpotential and impedance of the anode are higher than those of the cathode in the cells tested (even at low currents); this is contrary to that found in proton-exchange membrane fuel cells (PEMFC) and it shows that caution is required when translating prior understating of PEMFC to APEMFC. The working hypothesis is that there is flooding-derived mass transport loss at the anode (where water is electro-generated).
