Osaka Gas’ residential polymer electrolyte fuel cell (PEFC) cogeneration system
About Osaka Gas’cell evaluation technology

Achievements of Osaka Gas in long-term durability evaluation tests

Osaka Gas has been conducting long-term durability evaluation tests on PEFC since 10 years ago, covering the evaluation of fuel cells from more than eight manufacturers and an accumulated operating time of over 2 million hours. Osaka Gas has confirmed a durability of 90,000 hours on single cells and of 40,000 hours on cell stacks. From the long-term durability tests, Osaka Gas is accumulating cell evaluation know-how that includes identification of factors in degradation, establishment of degradation analysis techniques, elucidation of the degradation mechanism, and the collection of basic data for the accelerated degradation evaluation techniques. In addition, Osaka Gas allows its cell evaluation know-how to be used to a maximum in order to accelerate development work at manufacturers.
