Abstract

Microfabricated solid oxide fuel cells (SOFC) have been integrated onto silicon substrates. The SOFC membrane contained a sputter deposited 8YSZ electrolyte layer with a thickness of 750�nm. It is supported on the anode side by a nickel grid grown by electroplating. The grid has either a hexagonal or a spiderweb pattern with maximal free standing length of 80�?m and a height comprised between 4 and 6�?m. The SOFC membranes have diameter up to 5�mm and are mechanically stable up to 550��C. Completed with porous platinum anode and cathode, they show a maximal open circuit voltage (OCV) of 280�mV at 450��C, under a mixture of H2 and Ar at the anode. � 2008 Elsevier B.V.
