Environmental testing starts on stationary fuel cell generator

Tokuyama and Toyota start environmental tests for stationary fuel cell generator that uses by-product hydrogen

Tokuyama and Toyota Motor Corporation have commenced verification tests, using by-product hydrogen, of a stationary fuel cell generator (FC generator) that makes use of the fuel cell system (FC system) installed in the Mirai Fuel Cell Electric Vehicle (FCEV). The FC generator has been set up within the Tokuyama Factory grounds in Shunan City, Yamaguchi Prefecture. 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.

The newly introduced FC generator is based on the FC generator with a rated output of 100 kilowatts that has undergone verification tests since September 2019 at Toyota’s Honsha Plant grounds in Toyota City, Aichi Prefecture. The rated output has been changed to 50 kilowatts, and other enhancements have been made, such as adjusting the component layout to improve maintenance.

A feature of the new 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 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.

Through these tests, Tokuyama and Toyota will further advance efforts aimed at the realisation of a hydrogen society.
