Development of SOFC power generation module with high electrical generation efficiency

Abstract

This article reports on the development of a 3-kW class solid oxide fuel cell (SOFC) power generation module being developed jointly by NTT, Sumitomo Precision Products Co., Ltd., and Toho Gas Ltd. as an industrial stationary power generation system. NTT has been developing cell materials, anode-supported cells, and SOFC stack technologies. The 3-kW class SOFC power generation module uses two 40-cell SOFC stacks. This module provided long-term and maximum electrical efficiencies of 56% and 59%, respectively.
