POWER GENERATION FEATURE
achieving a significantly reduced emissions
profile, the companies said. " The
results of this project will provide key
insights into the capability of fuel cell
systems to scale and serve multi-megawatt
data centers, " said Randy MacEwen,
Ballard's president and CEO. " The project
will also explore the scalability of fuel
cell systems powered by low-carbonintensity
hydrogen from cost and performance
perspectives. "
From passenger cars to
power generators
Fuel cells originally developed for passenger
cars and since employed in commercial
vehicles are also finding use in generators.
Toyota and Hyundai both have
adapted their fuel-cell propulsion systems
for use in stationary applications.
Toyota has adapted its fuel-cell system
installed in the Mirai fuel cell electric
vehicle (FCEV) to create stationary
fuel-cell generators that have been in
operation for the past couple years. For
example, the car maker began verification
tests of an FC generator using byproduct
hydrogen within the Tokuyama
factory grounds in Shunan City in 2020.
The tests were 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), secondary battery
and air compressor, Toyota seeks to
produce a high-performance generator
at a reasonable price. Development on
the FC generator was carried out jointly
by Toyota and Toyota Energy Solutions.
The FC generator used at the
Tokuyama factory is based on a previous
model with a rated output of 100
kW that had undergone verification
tests at Toyota's Honsha Plant grounds
since September 2019. The rated output
has been changed to 50 kW and other
enhancements have been made, such
as adjusting the component layout to
improve maintenance. The companies
have been testing the use of hydrogen
generated as a byproduct in the manufacture
of sodium hydroxide by
Tokuyama, using the chloralkali process
as fuel for the FC generator.

Toyota has stated a goal of power-generation
efficiency (transmission end) of
50% or more. The company is verifying
and evaluating the unit's energy efficiency
- the amount of electricity generated
per unit of hydrogen - the stability of the
generated output, durability, and ease of
maintenance of the generator. Toyota
plans to expand its FC generator output
lineup while continuing to enhance efficiency
and durability, making it more
compact and reducing costs.
