However, problems such as poor anti\u2010poisoning of catalysts and serious fuel leakage have hindered the development of flexible DAFCs. In this study, a nanoporous gold \u2010loaded PtPdRhCo quaternary core\u2013shell catalyst is successfully prepared via a simple electrodeposition method. Consequently, the quaternary core\u2013shell catalyst exhibits superior mass activities for the ethanol oxidation reaction (25.20 A\u00b7mg\n                    <jats:sub>Pt<\/jats:sub>\n                    <jats:sup>\u22121<\/jats:sup>\n                    ), methanol oxidation reaction (19.30 A\u00b7mg\n                    <jats:sub>Pt<\/jats:sub>\n                    <jats:sup>\u22121<\/jats:sup>\n                    ), and oxygen reduction reaction (0.82 A\u00b7mg\n                    <jats:sub>Pt<\/jats:sub>\n                    <jats:sup>\u22121<\/jats:sup>\n                    ), respectively. On this basis, a flexible direct ethanol fuel cell (DEFC) is assembled with two carbon cloths containing catalysts and sodium polyacrylate\u2010sodium alginate hydrogel electrolyte between the two carbon cloths. Electrochemical tests show that flexible DEFC achieves a stable output potential of 0.55\u00a0V and a maximum power density of 17.68 mW\u00b7cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    .
