dc.description.abstract This work shows the development of anodes based Sr-doped LaCrO3 (LSC) for La5.6WO11.4-d;-based proton conducting fuel cells. The electrode was improved by considering the operation limitations of the LSC material, which is chemically compatible at high temperatures with La5.6WO11.4-d; in contrast with typically NiO-based composite anodes. Firstly, the synthesis of 10% Ce doped LSC material, its compatibility with LWO and superior conduction properties are presented. These properties make this composition suitable as anode material, although EIS analysis revealed that its operation is still limited by LF surface associated limiting processes. In order to improve the surface catalytic properties of the anode, Ni infiltration was conducted on sintered anode, resulting in the coating of the electrode surface with Ni nanoparticles and consequently in a further improvement of the anode performance. Specifically, the infiltrated anode with the highest Ni loading presents uniquely HF associated resistance and the Rp is 0.26 ohm cm2 at 750 ºC in wet H2. es_ES
