Tokyo Gas has been conducting intensive research and developments of fuel cells including polymer electrolyte fuel cell (PEFC). PEFC has desirable characteristics, such as easy start-up and shutdown, compactness and light-weight etc., for a small scale co-generation system (co-gen). Counting on them, R&D on natural gas fuelled PEFC co-gen for residential application in Japan has been conducted. Our activities relating to residential PEFC co-gen include establishment of a specification of PEFC co-gen fitting market requirements, development of integrated fuel processors, and evaluation of the performance through operation tests and field trials. In this paper, these activities towards the first market introduction is reported.
