Stepped gradient fuel electrode and method for making the same
Abstract
The present invention provides for a method of depositing a stepped-gradient fuel electrode onto a fuel cell support 2 and the resulting fuel cell, that comprises placing a solid oxide fuel cell support that has at least an air electrode layer 4 and an electrolyte layer 6 into an atmospheric plasma spraying chamber and measuring spray parameters of an atmospheric plasma spray to obtain reactive oxides, conductive metal and graphite phases. Then spraying the spray parameters onto the solid oxide fuel cell support to produce multiple sub-layers 8 on the solid oxide fuel cell support, and adjusting a hydrogen usage of the atmospheric plasma spray. The adjusting of the hydrogen usage comprises using high hydrogen levels for the initial spraying of the sub-layers producing a first gradient region, and a lower hydrogen level for subsequent spraying of the sub-layers, producing a second gradient region.
