Toyota's modular hydrogen fuel cell

60-80kW delivered at 400-750W, packaged as a cube or rectangular prism. (80kW = 107hp)

"Toyota City, Japan, February 26, 2021―Toyota Motor Corporation (Toyota) has developed a product that packages a fuel cell (FC) system into a compact module and plans to begin selling it in the spring of 2021 or later. The new module will be easily utilized by companies that are developing and manufacturing FC products for wide variety of applications, including mobility such as trucks, buses, trains and ships, as well as stationary generators (referred to hereafter as "FC product companies")."

How would the weight (250kg) compare to a 100-hp ICE drivetrain? Looking for "80kW generators" all I can find are enormous two ton diesel generators that are meant for permanent installation.

Probably twice as heavy as a Bolt drive unit that makes 200 hp - those should only weigh like 250 lbs. But the battery pack weighs 960 lbs.

Yeah, I'm talking about the whole drivetrain including energy storage. It would be interesting to know what the energy density of hydrogen gas is when fully compressed.

Overall this is a much more compelling solution than "e-fuel", in that it provides the scaleability and quick refueling of a chemical based fuel, and at the same time it will complement mainstream BEV drivetrains seamlessly.

Hydrogen home generators would be sweet too. Hack this down to a tenth of its size and you could still power a house.
