A novel design of single-chamber SOFC micro-stack operated in methane-oxygen mixture

Electrochemistry Communications

In this paper, a novel design of single-chamber solid oxide fuel cell (SC-SOFC) micro-stack with star-shape was presented and operated successfully in methane-oxygen mixture. This stack consisted of four anode-supported single cells connected in series, and generated a maximum power output of 421 mW (total active area: I cm(2)) at the furnace temperature of 750 degrees C, which powered an USB fan stably. The symmetric design can ensure the identical operation of each cell, and good capacity for scale-up of the stack. (C) 2008 Elsevier B.V. All rights reserved.
