Abstract

This work is a comprehensive analysis of the decal process for production of catalyst coated membranes. Both the process window for the transfer of electrodes from decal foil onto membrane and the effects of the parameters of ink and transfer process on structure and function including process reproducibility shall be investigated. A major component of all those aspects is the selection, implementation and assessment of appropriate characterization methods.

Abstract

Solid oxide fuel cells (SOFC) achieve high efficiencies, the lower the internal electrochemical losses are. This work investigates insulating secondary phases at the cathode/electrolyte interface that are formed during fabrication. Full cells and model systems are electrochemically characterized, analyzed by electron microscopy and reconstructed by tomography. A FEM model reveals performance limiting factors. As a result, an optimized production routine is proposed.
