Abstract

The invention discloses a method, device and application for rapidly preparing a membrane electrode driven by light. A polymer electrolyte membrane loaded with a metal macrocyclic compound is placed in a reaction device, and a platinum metal precursor and a reducing agent are added to the reaction pool. The mixed solution of platinum nucleates and grows rapidly on the polymer electrolyte membrane under light conditions to obtain a membrane electrode. This method has a simple process, can quickly prepare membrane electrodes, has good repeatability, and is easy to mass-produce membrane electrodes.
