Abstract
In fuel cells, the structure of electrodes is an important factor which effect the cell performance. To improve the structure and the performance of electrodes, a new method of providing fuel cell electrodes is proposed in this paper. PTFE (polytetrafluoroethylene) and ethyne black was ground for about half an hour in a high-speed grinder, then the catalyst was added into the grinder and milled for an hour. This milled catalyst was transferred into a mixer followed by the addition of surface-active agent. After a suspension was formed, it was filtered under vacuum condition.Then a thin uniform filter-cake of the catalyst was formed, which was rolled together with a current-collecting mesh and a gas-ventilating film. Finally, the gas-difusion electrode of fuel cells was obtanied.The polarization property of the hydrogen electrode has been measured, where the Hg/HgO was used as reference electrode. And the effect of hydrophobic ethyne black and PTFE on electrodes in fuel cells was investigated.
