Toward a stable and active catalyst for proton-exchange membrane water electrolysis

In this article, Chen Ling (senior principal research scientist at Toyota), Hongliang Xin (associate professor at Virginia Tech), and their colleagues exchange views on the significance, hurdles, and possible solutions associated with improving the catalysts for the acidic oxygen evolution reaction. These insights contribute to addressing challenges for the widespread adoption and use of proton -exchange membrane water electrolyzers.
