One of the most promising alternatives is hydrogen fuel cells, which use hydrogen to directly generate electricity via a reaction with oxygen, but the race is still very open as to which hydrogen ...

Common fuel cells use an electrode design that hasn’t changed in decades. The new research has catalyst ridges separated by empty grooves. This enhances oxygen flow and proton transport.

On to the H2 fuel cell The preferred approach to using hydrogen long term is the fuel cell. Fuel cells use a process that is essentially the reverse of electrolysis to combine hydrogen and oxygen ...

A fuel cell stack, or bank, serves as the ‘engine,’ where many cells facilitate a simple chemical reaction between oxygen from the air and the pressurized hydrogen fuel stored onboard the vehicle.

Hydrogen-oxygen fuel cells are an alternative to rechargeable cells and batteries. In a hydrogen-oxygen fuel cell, hydrogen and oxygen are used to produce a voltage. Water is the only product.

Hydrogen is a colourless, odourless, tasteless and non-toxic gas. When burnt it releases heat. Hydrogen can also be reacted with oxygen electrochemically in a fuel cell to produce heat and electricity ...
