Tokuyama and Toyota Start Verification Tests in Japan for Stationary Fuel Cell Generator
Verification tests have begun of a stationary fuel cell generator that makes use of a fuel cell system installed in the Mirai Fuel Cell Electric Vehicle (FCEV) using by-product hydrogen. The tests are scheduled to continue until the end of March 2022.
By using components from the Mirai FC system, such as the FC stack, power control unit (PCU), and secondary battery, Toyota seeks to produce a high-performance generator at a reasonable price.
A feature of the tests is the use of hydrogen generated as a by-product in the manufacture of sodium hydroxide by Tokuyama, using the chloralkali process as fuel for the FC generator.
Tokuyama will be responsible for the steady supply of by-product hydrogen, and the electricity produced by the FC generator will be supplied to the Tokuyama Factory at a rated output of 50 kilowatts.
Toyota will verify and evaluate aspects including the energy efficiency―the amount of electricity generated per unit of hydrogen―the stability of the generated output, durability, ease of maintenance of the generator, and the impact of salt-air damage from the sea breezes. In addition, the tests will be used to estimate the impact on power generation from the use of by-product hydrogen, and the economics of this in comparison with purchasing from an external source.
