摘要:

碱性聚电解质燃料电池(APEFC)近年来取得了可观的进展,但是在使用空气作为氧化剂工作时仍然面临着性能损失. 文献中已有多个理论试图解释性能损失的来源,但是缺乏定量化的分析. 本文根据实验发现和热力学及阳极反应的动力学分析,提出了分层的阳极碳酸化模型和方程组.模型的定量化模拟结果进一步和实验结果进行验证,提出了电池性能损失的可能原因.

Abstract:

The alkaline polymer electrolyte fuel cell (APEFC) has made appreciable progress in recent years but is still suffering performance loss during discharge with air as the oxidant. Several theories have been suggested to interpret the loss. However, efforts are still needed to reach a clear quantitative understanding. Based on the major experimental findings in combination with thermodynamics and kinetics of the reactions involved in the anode, this paper presents a model featuring layered carbonization in the anode and relevant grouped equations. The simulation results generated from the latter are compared with experiments, and possible principles to suppress the performance loss are proposed.

Key words: alkaline polymer electrolyte, fuel cell, carbonization, carbon dioxide, hydrogen oxidation reaction
