EH Group Engineering

Switzerland-based EH Group Engineering develops and produces hydrogen fuel cell stacks and fuel cell systems. According to the company, its unique fuel cell stack design (i.e. more compact and lightweight) results in higher system efficiencies. The company’s proprietary assembly process also reportedly reduces costs.

EH Group Engineering’s patented proton exchange membrane (PEM) fuel cell stacks are available in four models: “EH-31,” which generates 1–4 kilowatts (kW); “EH-51,” which generates 5–15 kW; “EH-81,” which generates 20–100 kW, and “EH-87,” which generates 150–320 kW. The company’s patented fuel cell systems can generate up to 300 kW of power, and their modular design allows room for customization depending on the application, such as for drones, forklifts, manufacturing equipment, commercial and other vehicles, and aircraft.

Key customers and partnerships

In June 2023, the company partnered with Ecomar Propulsion to integrate more than 200 kW of marinized fuel cells into Ecomar’s zero-emission marine powertrains. The EH Group has also partnered with SAFRAN (an aerospace technology provider) for its Hydrogen Explore program, SNAM to participate in its HyAccelerator program, and the European Space Agency BIC Switzerland program to develop its fuel cell technology for space applications.

Funding and financials

The company’s most recent funding was in January 2022, when it raised CHF 5 million (USD 5.5 million) in a pre-Series A round led by AP Ventures. In February 2020, EH Group Engineering received a EUR 1.5 million (around USD 1.6 million) grant from the European Commission to start mass production. The company was also selected as part of the 2020 CALSEED cohort, with a grant of USD 150,000, to apply its fuel cell technology and production process to electrolyzers.
