Products for Fuel Cell Electric Vehicles, etc.
Toyota Industries takes advantage of the technology and expertise that it has cultivated over the years, and develops and manufactures a variety of other products that excel in functionality and quality, including viscous type power heaters as well as components for fuel cell vehicles such as hydrogen circulation pumps and air compressors.
Products for Fuel Cell Electric Vehicles
The FCEV (Fuel Cell Electric Vehicle) is driven by electric motor with electricity generated by a chemical reaction between oxygen and hydrogen in the FC stack.
Air Compressor
The air compressor is supplying oxygen(Air) efficiently to FC stack with sucking and compressing oxygen(Air).
Our newly developed air compressor achieves 24% compression efficiency improvement, 35% weight reduction, and 45% size reduction from low flow rate to high flow rate compared to the previous model and contributes to improve vehicle acceleration characteristic and vehicle cruising distance. This was accomplished through adoption of a movable roller-type traction drive unit, the first of its kind to be used in a mass-produced product in the world.
(Specifications)
| Pump type | Accelerating turbo type |
|---|---|
| Maximum output | 24kW |
| Maximum speed | motor 16,700r/min impeller 183,700r/min |
Hydrogen Circulation Pump
The hydrogen circulating pump has a function of re-circulating hydrogen which has not been chemically reacted in the FC stack, for chemical reaction again and makes contribution for improving fuel efficiency.
Adopting a new seal structure improved the corrosion resistance of the pump and made it possible to switch its material from the previous stainless to aluminum, achieving 41% weight reduction and contributing to improve vehicle cruising distance.
(Specifications)
| Pump type | 2-lobes straight roots type |
|---|---|
| Maximum output | 1kW |
| Maximum speed | 7,200r/min |
Viscous Type Power Heater
The viscous type power heater, jointly developed by Toyota Industries and DENSO Corporation, provides supplementary heat generation for engines that produce low heat levels. This product shortens the time required for the engine water temperature to rise and allows the vehicle cabin to be heated quickly. In addition to achieving miniaturization and low cost by means of simplified construction, the viscous heater also relies on a friction-free non-contact mechanism to guarantee high reliability and safety.

| Dimensions (barrel diameter x length) | φ116×98mm |
|---|---|
| Weight | 1.2kg |
| Heat generation | 1.6kW |
