With dwindling passenger car sales for hydrogen fuel cells, the technology is now looking like a non-starter for heavy-duty ...

A single hydrogen fuel cell delivers a low voltage, so manufacturers "stack" fuel cells together in a series, as in a dry-cell battery. The more layers, the higher the voltage. Electrical current ...

“Using renewable electricity, 75 percent of that energy makes it to the wheels of a BEV,” says James Edmondson, research ...

This unit serves as a supplementary power source to the fuel cell stack. Like a large battery, the ultracapacitor recovers and stores energy generated during deceleration and braking. It uses this ...

Fuel-cell vehicles don't require charging at all ... So, how do hydrogen cars stack up in these areas? When it comes to recharging, hydrogen cars have battery-electrics beat.

Through continuous testing and refinement, Senergy has achieved incremental improvements in fuel cell stack power density that meets the ever-growing demand for higher performance and integration ...

The system is based on a solid polymer fuel cell stack which eliminates the need for an external humidifier, according to the manufacturer. The stack is internally humidified and dehumidified ...
