PROCESS FOR PRODUCING A SOLID OXIDE FUEL CELL BY DEPOSITING AN ELECTRICALLY CONDUCTIVE AND GAS PERMEABLE LAYER ON A POROUS SUPPORT SUBSTRATE

摘要

A process for depositing an electrically conductive, preferably perovskitic layer uses a pulsed sputtering process. The layer has a low diffusivity for the elements in the iron group and is especially suitable for use in solid oxide fuel cells (SOFC). An assembly of the electrically conductive ceramic layer on a porous support substrate is also provided.

1. A process for producing a solid oxide fuel cell, the process comprising the following steps:
providing a porous support substrate formed of sintered grains of a Fe-based alloy, the support substrate having an open-pore structure and being gas permeable; depositing an electrically conductive ceramic layer on the porous support substrate by a pulsed sputtering process retaining the open-pore structure of the substrate and a gas permeability thereof, forming a coated porous support substrate that is gas permeable; and applying an anode in direct material contact with the coated porous support substrate to produce a support structure with an anode of the solid oxide fuel cell.
