Hydrogen fuel cells have been a promising alternative powertrain technology for years, but they remain largely a peripheral discussion in the auto industry.
But now the world's largest auto parts supplier, Bosch, is doubling down on the technology, saying it plans for "large-scale production" of the fuel cell stacks that drive the powertrains.
Bosch said last week it has created a business unit and a key partnership that will bring an affordable integrated fuel cell system to market by 2022. The company has formed an alliance with Powercell Sweden, a manufacturer of fuel cell stacks.
The plan is for the partners to jointly produce the critical system component called polymer-electrolyte membranes, and then for Bosch to use its manufacturing resources to industrialize the systems around the world.
