Abstract A fuel cell is an energy conversion device that can continuously input and oxidant into the through electrochemical reaction to release electrical energy. Although noble metals show good activity in cell‐related reactions, their ever‐increasing price considerably hinders industrial application. Improvement of atom utilization efficiency considered one most effective strategies improve mass catalysts, this allows for use fewer saving greatly on cost. Thus, single‐atom catalysts (SACs) with 100% have been widely developed, which remarkable performance cells. In review, we will describe recent progress development SACs membrane electrode assembly applications. First, introduce several routes synthesis SACs. The mechanism involved reactions also be introduced as it highly determinant final activity. Then, systematically summarize application Pt group metal (PGM) nonprecious (non‐PGM) This review offer numerous experiences developing potential industrialized future.
