Screening and Properties of New Materials for MCFC Application

Abstract

A synthetic screening is given on interesting materials, dopants and protective coatings allowing a better control of the corrosion in MCFC systems and the optimization of their lifetime. After outlining the interest of MCFC systems with respect to other fuel cell devices, an analysis of the recent literature is given on electrolyte, cathode, anode and interconnection plate materials.

Input of atomic layer deposition for solid oxide fuel cell applications

“…In the well-known MCFC technology, thin layers are used as protective layers for the cathode avoiding its slow dissolution in the carbonate melt, as protective layers against the corrosion of the anode bipolar plate and as functional layers at the anode electrode (catalyst, sulfur sorbent, etc.). 65 The research group of Irvine is investigating a new kind of fuel cell, DCFC, combining the features of a SOFC system with a reservoir of a molten alkali carbonate at the anode side, thus enhancing the transport of the carbon fuel to this electrode. This is a hybrid concept between the MCFC and SOFC technologies.…”
