ABSTRACT
This work reports the results of using a Dynamic Hydrogen Electrode (DHE) as a reference electrode for performance measurements in an Proton Exchange Membrane Fuel Cell (PEMFC) operated at high temperature conditions and low relative humidity (T = 120 ºC y HR = 23 %). The performance of PEMFC was measured by using a composite membrane (SBA-16) and the results compared to those obtained with a commercial Nafion-115 membrane. The reference electrode was made using a platinum black deposit on the platinum wire surface. The DHE was introduced in the PEMFC close to the cathode electrode and it was stable under fuel cell operation. The kinetic parameters of anode and cathode reactions were estimated in a separated way.
