Intelligent Energy Develops 100 Kilowatt Fuel Cell Stacks

Intelligent Energy, the energy technology group involved in fuel cells, has developed a new 100-kilowatt (134 horsepower) automotive fuel cell architecture.

The company said it provides vehicle manufacturers with a new high performance option for their next generation of Fuel Cell Electric Vehicles (FCEVs).

Designed to deliver primary motive power within an advanced electric driveline, the 100 kilowatt fuel cell architecture and core technology will be made available to vehicle manufacturers through technology licensing programs and joint development agreements, stated the company in a press release.

The 100 kilowatt platform, as explained by the company, takes full advantage of Intelligent Energy’s stack technology, which offers power density of 3.5 kilowatt per liter (volumetric) and 3.0 kilowatt per kilogram (gravimetric), while being engineered for low cost, high volume series production.

The key enabler for this performance is stated as being the company’s proprietary, evaporatively-cooled (EC) technology. Compared to conventional liquid-cooled fuel cell stacks, the EC design is said to remove the need for individual cooling channels between each cell; this delivers a considerable advantage in terms of stack mass and volume.

“Our capability and proven technology provides a cost-effective opportunity for any vehicle manufacturer without a presence in this fuel cell power-band to jump ahead of its competitors,” said James Batchelor, Managing Director of Intelligent Energy’s Motive division. “Our 100 kilowatt platform provides automotive OEMs with a fast-track route to our next generation evaporatively-cooled stack technology, integrated into a compact system architecture. The concept, design, technology elements and IP package are all in place to enable the platform to be applied to customer vehicle programs today.”

As a side note, Intelligent Energy has been associated for over eight-years with the Suzuki Motor Corporation. The collaboration has seen the introduction of the world’s first type approved fuel cell powered scooter, powered by 4 kilowatt fuel cell systems that are based on Intelligent Energy’s complementary air-cooled (AC) technology. The two companies have also established a joint venture business that manufactures stacks and fuel cell systems from a ready to scale production facility in Japan.
