EFFECT OF NAFION LATEX TAKEN AS ELECTRODE ADDITIVE ON DISCHARGE PROPERTY OF ION EXCHANGE MEMBRANE FUEL CELLS

The ion exchange membrane fuel cell, as a kind of ideal generate electricity apparatus of hydrogen energy, is the key in the research and exploitation of hydrogen energy at present. The effects of Nafion latex taken as the electrode additive on the electrochemistry properties of the ion exchange membrane fuel cells are experimentally studied. The research results show that the electrical catalysis of the electrodes can be enhanced evidently when some Nafion latex is added into the electrodes. The discharge voltage and current density are in the peak state when the Nafion latex contents are within 3% to 5%. The Nafion latex prepared by different methods has the different effects on the discharge voltage and current density of the ion exchange membrane fuel cells.
