Toyota has created new electrolysis gear to make hydrogen from electrolyzing water employing the fuel cell (FC) stack and other technologies from the Mirai. The gear will be place into operation this March at a DENSO Fukushima Corporation plant, which will serve as a technologies implementation venue to market its widespread use going forward.

Toyota will accelerate its efforts to develop a model for the regional consumption of locally made hydrogen, employing electrolysis gear to make clean hydrogen and combust it in one particular of the plant’s gas furnaces.

The hydrogen utilization at DENSO Fukushima will be implemented as a project subsidized by the New Power and Industrial Technologies Improvement Organization (NEDO).

Toyota has positioned hydrogen as a essential fuel for advertising initiatives aimed at minimizing CO2 emissions to contribute to attaining carbon neutrality. In performing so, it aims to market the use of hydrogen not only by way of fuel cell electric cars (FCEVs) such as passenger vehicles, industrial trucks, and buses, but also by way of the widespread use of fuel cell (FC) items, such as the improvement and test operation of FC stationary generators. To this finish, Toyota is operating with numerous sector partners in the locations of making, transporting, storing, and employing hydrogen.

Toyota has been employing hydrogen for FCEVs, FC stationary generators, production at plants, and so on. to date. It has also promoted transporting activities, such as the improvement and manufacturing of FC trucks for hydrogen transportation. In the future, Toyota hopes to contribute to expanding choices for making hydrogen employing biogas generated from livestock manure in Thailand in addition to building electrolysis gear.

The electrolysis gear, which utilizes the FC stack from the Mirai and Sora FC bus, is newly created gear that requires benefit of each the technologies Toyota has cultivated more than a lot of years of FCEV improvement and the information and knowledge it has accumulated from a range of usage environments about the planet. The unit installed at DENSO Fukushima can make about eight kg hydrogen per hour, with 53 kWh/1 kg hydrogen power necessary.


The cells made use of in the Proton Exchange Membrane (PEM) electrolysis stack are hugely trusted, backed by the mass production and usage benefits of far more than seven million cells (adequate for about 20,000 FCEVs) considering that the initially-generation Mirai was launched in December 2014.


Toyota has made use of titanium for the stack separator, which was created for FCEVs and has been made use of considering that the initially-generation Mirai. It was created to enhance the durability that is necessary of electrolysis gear employing titanium’s higher corrosion resistance keeping virtually the identical level of functionality even soon after 80,000 hours of operation so that it can be made use of safely more than a extended period of time.


Electrolysis gear configuration

Extra than 90% of FC stack elements for FCEVs and FC stack production facilities can be made use of/shared in the PEM electrolysis stack production method. This will permit for mass production to attain a expense level that enables its widespread use. Additionally, it substantially shortens the improvement period by employing the technologies, information, and expertise accumulated more than a lot of years of FCEV improvement.
