摘要：A photoassisted oxygen reduction reaction (ORR) through I⁻/I₃⁻ redox couple was investigated for proton exchange membrane (PEM) fuel cell cathode reaction. The I⁻/I₃⁻-based liquid cathode was used to replace conventional oxygen cathode, and its discharge product I⁻ was regenerated to I₃⁻ by photocatalytic oxidation with the participation of oxygen. This new and innovative approach may provide a strategy to eliminate the usage of challenging ORR electrocatalysts, resulting in an avenue for developing low-cost and high-efficiency PEM fuel cells.
