Abstract

The influence on electric properties of three different types (OC, HC and DC) of electrode/matrix interfaces produced in a phosphoric acid fuel cell by direct tape-casting of a matrix based on SiC whisker on an anode, a cathode, or both electrodes was investigated. Different current densities at operating potentials were obtained according to the cell type. This indicates that the different interface characteristics influenced the current/voltage behavior. OC exhibited the highest current density at 503 mA cm-2 at 0.7 V.
