Abstract :

Electrolysis of water is a convenient way to store energy as hydrogen. The PEM Electrolysis Cell (PEMEC) has many advantages; Compactness, operation in a wide power range, and the possibility of deliver high purity H2. However, the use of expensive iridium on the anode side (oxygen electrode), makes large scale operation of the PEMEC too costly. In order to reduce the cost it is necessary to either replace or at least lower the use of iridium. Here we for the first time report the use of Mg-doped LaCrO3 as a possible support material for the PEMEC oxygen electrode. The chromates are synthesized using aqueous solutions of metal-nitrates, evaluated by powder XRD, tested for corrosion stability in acid and finally the total conductivity is measured. The compounds show good corrosion stability and sufficient conductivity.
