On the upcoming IAA Transportation present in Hanover, Schaeffler will current a hydrogen gasoline cell demonstration automobile constructed from the bottom up on the premise of an electrical van. The automobile is pushed by a Schaeffler 3in1 e-axle powered by a gasoline cell system made utilizing Schaeffler elements.
Schaeffler collaborated with REFIRE, a number one world provider of business hydrogen gasoline cell applied sciences. The electrical axle, gasoline cell stack, management system, and vitality administration system had been all designed and constructed by the e-mobility consultants at Schaeffler.
Schaeffler is presenting the automobile for instance of optimum interoperability between electrical drive, gasoline cell, and lithium-ion battery know-how.
Initially, gasoline cell drives can be used primarily in long-haul business autos. Vans will profit from this know-how too as a result of they usually additionally cowl longer distances.

The varied elements and programs that make up gasoline cells embody bipolar plates. These plates are integral elements of the gasoline cell stack, accounting for as much as 80% of stack weight and as a lot as 65% of stack quantity, regardless of every plate being solely 50 to 100 microns thick.
Schaeffler has been creating metallic bipolar plates since 2017 and is at the moment making them at a pilot plant at its Herzogenaurach location. The method of producing bipolar plates attracts on the corporate’s in depth experience in a number of manufacturing processes, together with chilly forming, stamping, becoming a member of, and floor therapy.
For Schaeffler, creating processes corresponding to forming and coating for very skinny metal elements like bipolar plates has largely been a case of adapting processes that it has already been utilizing for a few years within the manufacture of motor and transmission elements.
Schaeffler can also be leveraging its bearings know-how to develop varied axial and radial air foil bearings for gasoline cell air provide, nozzles for hydrogen recirculation, and key elements for the coolant administration system, together with a thermal administration module and good valves for decentralized coolant regulation. As well as, the corporate is regularly rising its experience and capabilities in gasoline cell system management, together with software program modules for gasoline cell-specific capabilities.
The automobile on the IAA Transportation present contains a 13 kWh battery with a most energy output of 85 kW, and a gasoline cell system rated for a steady output of fifty kW. Propulsion is offered by a Schaeffler 3in1 e-axle, full with energy electronics, with a most output of 140 kW. Schaeffler is utilizing the automobile as a improvement platform for testing and optimizing the interplay between the assorted system elements.
By partnering with Symbio, a hydrogen know-how three way partnership between Faurecia and Michelin, to ascertain Innoplate, Schaeffler goals to transition its bipolar plates into industrial manufacturing in the beginning of 2024. The companions within the Innoplate three way partnership intend to provide plates for each cell and stationary purposes. The joint manufacturing facility can be positioned in Haguenau, France, and can initially have an annual output of 4 million plates, rising to roughly 50 million by 2030.
To confirm the feasibility of producing its bipolar plates on an industrial scale, Schaeffler arrange a pilot manufacturing plant in the beginning of 2022. The plant is designed in such a approach that it may be used to fabricate bipolar plates in sizes ranging as much as the bigger 1,800 by 600 mm codecs utilized in electrolyzers.
The person course of steps carried out by the pilot plant, which was designed in partnership with Schaeffler’s in-house Particular Equipment unit, are already absolutely automated. The pilot plant is a part of a brand new hydrogen middle of excellence on the firm’s Herzogenaurach location, which incorporates a big testbed for testing electrolyzer and gasoline cell applied sciences on the part, stack, and full system ranges.
