For trucks, buses, trains or ships as well as stationary generators
Toyota also wants to sell the fuel cells from the Mirai to other companies in the future. More precisely: not just the stacks, but also the technology around them. Toyota introduces itself as customers to companies that want to equip their trucks, buses, trains or ships with them.
The press release does not reveal whether the Japanese would also supply other automakers. In addition to mobile applications, the modules should also be suitable for stationary generators.
So far, Toyota has not only had fuel cell cars like the Mirai or the Sora fuel cell bus built, but also sold the fuel cell technology to other companies. Apparently, companies from many industries are looking for fuel cell systems that can be easily adapted to their own products.

Toyota has therefore now "developed a product that combines optimized system components from the Mirai, such as the fuel cell stack, as well as other components for air and hydrogen supply, cooling and power control in a single compact module." The new module is available in four versions: in a vertical (Type I) and a horizontal version (Type II), each with 60 or 80 kW output.
Type I (vertical design)
Type II (horizontal design)
| Vertical version (type I) | Horizontal version (type II) | |
| Dimensions (length / width / height) | 890/630/690 mm | 1,270 / 630/410 mm |
| Weight | approx. 250 kg | approx. 240 kg |
| rated capacity | 60 or 80 kW | 60 or 80 kW |
| voltage | 400-750 V | 400-750 V |
The new module offers a large voltage range (400 to 750 volts) and, thanks to a built-in fuel cell "boost converter", can be connected directly to an existing electrical device that has a motor, inverter and battery, etc. This simplifies the design and manufacture of fuel cell products, according to Toyota. The four variants can be combined depending on the application and can be flexibly adapted to the required performance level and the available space.
The fuel cells work with hydrogen and high voltage. Vehicle technology security measures have been taken to ensure safe operation. This includes, in particular, preventing leaks and immediately recognizing and stopping leaks, according to Toyota. The module should work reliably and safely even at high and low temperatures, at high altitudes with a low oxygen content in the air and in applications with strong vibrations.
Customers can also request technical support from Toyota engineers who will help determine the optimal layout to optimize efficiency, service life, operating costs, and more.

The new module should offer "a first-class power density per unit volume"; Toyota does not give a value. One of the special features is that the fuel cell system works without a humidifier, as the water produced circulates within the fuel cell stack. In addition, maintenance work should be simple and rarely required. The compact modules are expected to be sold in Japan this spring. Toyota did not say what such a module costs; Probably the price is a matter of negotiation, whereby the number of pieces and other marketing considerations play a role.
