Toyota has developed new electrolysis equipment to produce hydrogen from electrolyzing water using the fuel cell (FC) stack and other technology from the Mirai. The equipment will be put into operation at a DENSO Fukushima Corporation plant.
The electrolysis equipment, which utilizes the FC stack from the Mirai and Sora FC bus, is newly developed equipment that takes advantage of both the technology Toyota has cultivated over many years of FCEV development and the knowledge and expertise it has accumulated from a variety of usage environments around the world. The unit installed at DENSO Fukushima can produce approximately 8 kg hydrogen per hour, with 53 kWh/1 kg hydrogen energy required.
Toyota has used titanium for the stack separator. It was developed to improve the durability that is required of electrolysis equipment using titanium’s high corrosion resistance maintaining almost the same level of performance even after 80,000 hours of operation so that it can be used safely over a long period of time.
