Abstract

An solid oxide fuel cell anode is oxygen tolerant at elevated temperatures through the use of a noble metal catalyst. The anode may be formed of a three-dimensional solid phase having an electrocatalytic noble metal phase of a plurality of noble metal particles and an ion conducting phase of a plurality of ionic conductor particles. The mean size of the noble metal particles is larger than the mean size of the ion conductor particles.
