Recent Progress of SOFC-GT Combined System with Tubular Type Cell Stack at MHI

Abstract

A solid oxide fuel cell (SOFC) is a fuel cell that can operate at high temperature. By applying its high-temperature exhaust heat to gas turbine (GT) combined-cycle power generation, an extremely high-efficiency thermal power system can be constructed, with a power generation efficiency of up to 70%. Mitsubishi Heavy Industries, Ltd. (MHI) is one of the first companies to focus on the potential of the SOFC as a component of large-scale power generation systems and has promoted both element and system development since the 1980s. New 250kW-class SOFC-MGT Hybrid System has been under trial operation since November 2012.
