The 260-pound fuel cells combine oxygen and hydrogen to produce electricity for the shuttle's systems.

Fuel cells, which produce electricity by combining hydrogen with oxygen from the air, offer still greater potential for increasing range.

Cars powered by fuel cells combine hydrogen and oxygen from the air in a chemical reaction.

He cannot control the temperature of water or combine hydrogen and oxygen to create water.

Fuel cells combine hydrogen and oxygen to form electric current and water, with high efficiency and no pollution.

Combining hydrogen and oxygen to generate electricity, fuel cells are typically made up of many small units, clustered in stacks.

Instead it uses a fuel cell, which makes electric current by combining hydrogen with oxygen.

The devices combine hydrogen and oxygen to make electricity, with water as a byproduct.

Palladium plays a key role in the technology used for fuel cells, which combine hydrogen and oxygen to produce electricity, heat, and water.

Fuel cells make electricity by combining oxygen and hydrogen.
