DEVELOPMENT OF PLASMA SPRAYED COMPONENTS FOR A NEW SOFC DESIGN

摘要

The vacuum plasma spraying technique has been further developed and adapted to manufacture the central multilayer MEA component in one consecutive spray process. This enables a new SOFC design with a supporting porous substrate, porous electrode layers with graded composition and porosity and a thin, dense electrolyte layer. The features and specific properties of the vacuum plasma spray process and the adaptation of the SOFC design corresponding to the production method are reported. The state of the development of plasma sprayed MEA layers and of the entire multilayer MEA compound are presented.
