Intelligent Energy showcasing 100kW hydrogen fuel cell architecture at JSAE Automotive Engineering Exposition
The company’s unique stack technology offers leading power densities of 3.5 kW/l (volumetric) and 3.0 kW/kg (gravimetric), while being engineered for low-cost, high-volume series production. Intelligent Energy’s 100kW architecture will be available to vehicle manufacturers through technology licensing programs and joint development agreements.

Our proprietary, evaporatively-cooled (EC) technology is a crucial enabler for achieving new, high stack power densities. Intelligent Energy’s EC design negates the requirement for individual cooling channels between cells. This reduces the mass and provides packaging and weight advantages when compared to conventional liquid-cooled fuel cell stacks.—James Batchelor, Intelligent Energy’s Motive managing director
Thermal management for the EC fuel cell stacks removes heat generated during the electrochemical process via the evaporation of injected water. This approach eliminates the need for a humidifier and a separate stack cooling loop as used on other fuel cell systems, resulting in both a simplified system balance-of-plant (BOP) and reduced fuel cell stack size and weight.
The EC fuel cell stack and system design feature robust, thin bipolar metallic plate construction, an innovative fluid and power management architecture, and smart control system software. The overall result is a compact and power dense system that requires fewer balance of plant components than conventional fuel cell systems, the company says.
Intelligent Energy has an existing collaboration with Suzuki Motor Corporation. The partnership introduced the world’s first type-approved fuel cell powered scooter, which utilizes Intelligent Energy’s 4kW fuel cell systems. The two companies have also established a joint venture that manufactures stacks and fuel cell systems from a ready to scale production facility in Japan.
