Toyota Motor Corporation and Hino Motors, Ltd. have built a new version of their fuel cell bus. The new bus was developed jointly by Toyota and Hino based on a Hino hybrid non-step route bus and is equipped with the Toyota Fuel Cell System developed for the Mirai fuel cell vehicle. (Earlier post.)
The two companies leveraged their accumulated specialized technologies and expertise, with Toyota being responsible for development of the Toyota Fuel Cell System, while Hino handled development of the bus body, including the chassis. The new fuel cell bus is scheduled to service the Toyota Oiden bus route in Toyota City from 9 January.
The new fuel cell bus is equipped with eight 480-liter high-pressure hydrogen tanks as well as two 114 kW fuel cell stacks and two 110 kW, 335 N·m motors to provide increased output. The fuel cell hybrid bus uses a NiMH battery.
The bus also features a system for supplying electric power to buildings and other facilities during emergencies, which was enhanced through rigorous verification testing beginning in November 2013. Maximum output/voltage is 9.8 kW/DC300 V.
Toyota and Hino will verify the feasibility and effectiveness of the fuel cell bus through testing involving commercial operation on regular routes on public roads and will feed back the results into R&D. Hydrogen fueling of the bus will be carried out at Toyota Ecoful Town, under a New Energy and Industrial Technology Development Organization project.
The verification testing will be conducted with the cooperation of Toyota City as a part of public fuel cell bus road trials and emergency external power supply testing that began in 2010 under the Toyota City Low-Carbon Verification Project, which has been selected as one of the Next-Generation Energy and Social System Demonstration Projects being promoted by the Ministry of Economy, Trade and Industry.
During the international conferences that will be held during Toyota City’s Toyota World Environment Week (10-18 January), a fuel cell bus will be used as a shuttle between event venues on 15 January and demonstrations of the emergency external power supply system will be conducted from 14-18 January at Toyota Ecoful Town.
