While hydrogen has limited use in energy markets today, significant growth is possible in grid storage and as an energy carrier in other sectors. Along with lower electricity prices, further hydrogen cost reduction can enable electrochemical water splitting, particularly as the use of intermittent, renewable power sources increases and the quantity and duration of storage requirements limit electrical storage options. With the improved viability of large-scale hydrogen production, research in low temperature electrolysis has dramatically increased. The overwhelming majority of research efforts within proton exchange membrane-based systems has focused on catalyst development, although a smaller set have developed transport layers as well. As proton exchange membrane-based electrolysis shifts into higher technology readiness levels, however, there is a growing need for work optimizing materials integration, developing component-specific and device-level accelerated stress tests, and addressing manufacturing considerations. These areas directly impact electrolyzer performance, durability, and cost, and are critical to advancing hydrogen’s value and electrochemical water splitting.

虽然氢在当今能源市场中的使用有限，但在电网存储和作为其他部门的能源载体方面可能会出现显着增长。随着电价的降低，进一步降低氢气成本可以实现电化学水分解，特别是随着间歇性可再生能源的使用增加以及存储要求的数量和持续时间限制了电力存储选择。随着大规模制氢可行性的提高，低温电解的研究显着增加。在基于质子交换膜的系统中，绝大多数研究工作都集中在催化剂开发上，尽管较小的一组也开发了传输层。然而，随着基于质子交换膜的电解转向更高的技术准备水平，对优化材料集成、开发特定组件和设备级加速压力测试以及解决制造问题的工作的需求不断增长。这些领域直接影响电解槽的性能、耐用性和成本，并且对于提高氢的价值和电化学水分解至关重要。
