Toyota Fuel Cell System (TFCS) was aimed to realize the world’s first truly practical FCV, which would be capable of demonstrating the potential of FCVs. TFCS was adopted in MIRAI, enhanced the excellence of FCV, which had the reputation remarkably so far and Toyota drastically reduced the cost of the FC system, which is one of the largest obstacles to the commercialization of FCVs. This paper describes the development of the TFCS and its components, focusing on the approaches taken to accomplish this reduction in cost.
