PREPARATION OF POROUS ELECTRODES AND LAMINATED ELECTRODE-MEMBRANE STRUCTURES FOR POLYMER ELECTROLYTE FUEL CELLS (PEFC)

摘要

Porous Nafion-PTFE-bonded gas-diffusion electrodes (GDEs), for use in (PEFC), were prepared by a cold rolling process. In this process, no solvents are required. The raw material for the production of these electrodes is a ternary mixture of Nafion, PTFE and Platinum-loaded carbon blacks. Development goal of our recent activities is the optimisation of the raw material composition with respect to the structural and electrochemical properties of the electrode. [References: 6]
