Toyota Fuel Cell Technology

PEM technology at the heart

Toyota fuel cells use PEM (Proton Exchange Membrane) technology. A proton exchange membrane fuel cell transforms the chemical energy liberated during the electrochemical reaction of hydrogen and oxygen to electrical energy. It produces no emissions, except water. Moreover, using a unique Toyota technology, part of this produced water is diverted back to the membrane to humidify it. This is why the Toyota Fuel Cell Module does not need a separate humidifier.

Our fuel cell modules

To expand the potential of hydrogen from cars to other uses, we have repackaged our fuel cell technology into compact fuel cell modules. The main components (the fuel cell stack and components that handle air supply, hydrogen supply, cooling, and power control) are thus integrated in a compact package which can be easily adapted into a variety of products and applications.

The modules are available in two shapes – a box and a flat, rectangular shape – to allow greater flexibility and easier adaptation into new applications. Two variations for each shape allow a rated output of either 60 kW or 80 kW.

Local manufacturing

Since 1992, we have continued to refine our hydrogen technology. Our second-generation fuel cell modules are also assembled at TME’s R&D centre in Brussels. Since January 2022, the facility houses a pilot assembly line combining advanced technologies with high-quality assembly. The decision to assemble in Europe is to meet demand across the region, which is expected to grow significantly. In collaboration with entrepreneurs interested in using our technology in their applications, TME’s Fuel Cell Business Group is offering the necessary engineering support for integration.  

Versatile product line up

Our new fuel cell module has a wide voltage range (400 to 750 V). It can be connected to an electrical instrument thanks to its built-in fuel cell boost converter that simplifies the development and manufacture of fuel cell products. A modular approach improves convenience: the four models can be combined to match the output level and installation space available. Modularity also eliminates the need to create designs for individually installing and connecting fuel cell system-related components. And it decreases the number of locations the module must be connected to a device, which eases installation. 

Excellent safety and reliability

To ensure safety relating to the use of hydrogen and high voltage, we implement a range of precautions. These ensure that hydrogen does not leak. However, in the unlikely event that a leak should occur, it is immediately detected and stopped. The module is designed to work in diverse operating environments, including low and high temperatures, at high (low oxygen) altitudes, and in high-vibration conditions. Fuel cell product companies interested in using our modules can request the support of experienced engineers to help determine optimal design for fuel economy, usage duration, running cost, etc. 

High output and economic efficiency

Thanks to the characteristics of our compact fuel cell system, which eliminates a vehicle’s humidifier by circulating the water generated during power generation inside the fuel cell stack, our new fuel cell module has achieved a world-class, top-level output density per unit volume. The maintenance requirements of the new module are simple and infrequent. This helps to reduce the total cost, from procurement and usage to disposal.
