波动性电源条件下PEM制氢电解槽核心材料耐久性研究建议

Refl ections on Durability Research of PEM Water Electrolysis Stacks Based on Fluctuating Power Input

通过可再生能源进行制氢,用于传统高碳行业,是完成化石能源替代,实现“双碳”目标的重要途径。绿氢装备中,质子交换膜(PEM)电解槽响应快,调节范围广,与波动性可再生能源有着良好的适配性,是当前氢能领域研究热点。当前PEM电解槽的研究以大型化、低成本为主要目标,对于风光这一类波动性电源输入条件下,电解槽性能的稳定性、长周期运行下的衰减和老化机制研究不足,本文就风光波动性输入条件下PEM制氢电解槽耐久研究提出思考和建议。

Applying hydrogen from renewable energy to conventional carbon-intensive industries is an important method to realize fossil energy substitution and carbon neutrality goals.Among green-hydrogen equipments,proton exchange membrane(PEM)electrolyzer provides fast response and wide power range which fits well with the fluctuating renewable energy and has become research focus now.The study on PEM electrolyzer is currently concentrated on large scale and low cost,nevertheless study on the durability and degradation mechanisms over a long period is absent of PEM electrolyzer coupled with fluctuating sources such as wind and solar power.In this paper,reflections are proposed on durability study of PEM electrolyzer in terms of fluctuating input from wind and solar power.
