As if FCV aren't costly enough adding a turbo will add few $thousand more. Interesting nonetheless.


Two-Stage Electric Compressor for Fuel Cell Electric Vehicles

Garrett’s high-pressure ratio Two-Stage electric compressor significantly increases the power density of Proton Exchange Membrane (PEM) fuel cells while reducing compressor noise, allowing this clean energy technology to be applied to modern passenger vehicles.

INCREASED POWER & EFFICIENCY IN A QUIET, COMPACT DESIGN

Our efficient, powerful and lightweight compressor fuses leading-edge aerospace and automotive technologies to boost next-generation fuel cells and promoting the adoption of zero-emission vehicles.

Our Two-Stage Electric Compressor for Fuel Cell Electric Vehicles

Garrett’s Two-Stage compressor enables automakers to optimize electric powertrain potential by boosting hydrogen fuel cell stacks to higher pressures and flows within a downsized package that fits inside regular vehicles.
Advanced bearing and electrical system designs increase performance, reduce size, weight, and noise, and help make the vision of zero-emissions vehicles a reality.

Hydrogen Fuel Cell Vehicles to Accelerate Electrification in the Global Auto Industry

The auto industry is investing in a new powertrain revolution using electrification. Although sometimes positioned as competing technologies, an evolving narrative we support recognizes that neither BEVs nor FCEVs by themselves can provide for all zero-emissions transportation needs during the next several decades.

Coupled with more efficient internal combustion engines and hybrid powertrains, the leap to an electrified automotive future will likely see both BEVs and FCEVs in different uses and duty cycles across passenger and commercial vehicle segments.

Key Features

Garrett’s design innovations have helped reduce the size of hydrogen fuel cell stacks by 40 percent over predecessor systems, simultaneously generating significant gains in constant power ratings.
Our Two-Stage compressor can operate up to 20kW continuously and supply air at over 4 bar, helping to increase in stack power density.
Proprietary airfoil bearings result in a dramatic reduction in compressor noise, and run without oil, eliminating the risk of fuel cell stack contamination.

The idea is that higher pressure operation means more specific power. For the same amount of power out a smaller fuel cell stack + turbine is smaller/lighter/less expensive that the larger stack that would be required sans turbine. If that does not turn out to be the case then they aren't going to sell many.

IMO hydrogen cars are dead so the application for this would be in trucks, maritime etc.
