Liebherr and GM to Develop HYDROTEC Fuel Cell Power Generation System

This demonstrator will be based on GM’s HYDROTEC hydrogen fuel cell technology. The construction and testing of this demonstrator will take place in a laboratory specializing in multi-system integration testing at Liebherr-Aerospace in Toulouse, France. The demonstrator will incorporate GM’s precision engineered fuel cells, the HYDROTEC power cube and fuel cell system, as well as GM’s controls and models.

GM, a leader in fuel cell technology, and Liebherr, with its expertise in technological integration into aircraft, are pooling their skills for this project. Less emissions and less noise than operating conventional aircraft: With these advantages of the fuel cell, among others, both companies see a great opportunity for use in aviation. GM, through its relationship with Honda, is one of the world’s most advanced fuel cell developers in many industrial fields, now entering aerospace.

GM’s fuel cell business benefits from decades of investing in engineering and manufacturing expertise with high-volume processes that can bring economies of scale to fuel cell production.

“Airplanes are an excellent litmus test for the strength and versatility of our HYDROTEC fuel cells,” said Charlie Freese, executive director of GM – Global HYDROTEC. “Our technology can meet customer needs in a wide range of uses – on land, at sea, in the air or on rail, and this collaboration with Liebherr could open up new possibilities for aircraft in transition to fuel sources. alternative energy.

Liebherr is one of the world’s leading suppliers of integrated on-board systems for aircraft. Liebherr’s integrated aircraft system concept benefits from decades of investment in thermal management and on-board energy management.

“The switch from the conventional system to a power generation system based on hydrogen technology means major changes to the systems on board the aircraft that could lead to better and more efficient performance of the aircraft,” said explained Francis Carla, Managing Director and CTO, Liebherr -Aérospatiale & Transport SAS. “This is what we want to prove and test thoroughly. The advantage of GM’s HYDROTEC fuel cell technology is that it has shown promise in large automotive and military programs, where it has proven to be reliable from an engineering and manufacturing perspective We develop low-emission aerospace solutions.
