Silicon-based and silicon-containing materials have been used in polymer electrolyte membrane fuel cells (PEMFCs), solid oxide fuel cells (SOFCs) and phosphoric acid fuel cells (PAFCs). In this work the use of silicon in the membrane electrode assembly (MEA) of fuel cells is reviewed.

Abstract

Silicon, silicon-based and Si-containing materials are widely used and play different roles in fuel cells. These materials have been used overall in polymer electrolyte membrane fuel cells, but also in solid oxide fuel cells and phosphoric acid fuel cells. The most used Si compounds in fuel cells are SiO₂ and SiC. In this work an overview of the use of Si-based and Si-containing materials in the membrane electrode assembly of fuel cells is presented.
