▎ 摘　　要

NOVELTY - The composite electrode has graphene, an electric catalyst and a Nafion. The composite electrode fuel cell is provided with mass content of the graphene alkene is 10-80 %, mass content of electric catalyst is 5-75 %, and mass content of Nafion is 5-30 %. The single cell operation dynamic state of voltage fluctuation range and stable state operation of the voltage fluctuation range is 2-40 mV. USE - Composite electrode. ADVANTAGE - The dynamic stability response of the electrode is increased. The mass transfer performance of catalyze layer is improved. The preparation process is simple. The composite electrode price is low. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method for composite electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the porous composite electrode structure. (Drawing includes non-English language text)
