Hydrogen Production Technology for a PEFC System from City Gas

Abstract

Tokyo Gas and other gas companies have developed the hydrogen production catalysts and fuel processing systems (FPS) for a lkW class residential PEFC system. High efficiency and compactness of FPS have been achieved by the integration of some hydrogen production processes. In addition, the durability for about ten years has been confirmed by the demonstration of 4,000 daily start and stop (DSS) operations and the accelerated tests for 40,000 hours.
