Energy storage hydrogen and oxygen fuel cell

What are the benefits of hydrogen and fuel cells?

These technologies will contribute significantly to a reduction in environmental impact, enhanced energy security (and diversity) and creation of new energy industries. Hydrogen and fuel cells can be utilised in transportation, distributed heat and power generation, and energy storage systems.

What are hydrogen-oxygen fuel cells?

Hydrogen-oxygen fuel cells are devices that generate electricity through a chemical reaction between hydrogen and oxygen, with Sir William Grove demonstrating the fundamental idea in 1839.

What is a hydrogen fuel cell?

Research is going on vehicles powered by hydrogen (13). As compared to a battery, a fuel cell has to be refilled constantly with an “energy-rich” substance, such as pure hydrogen in a hydrogen-oxygen fuel cell. In hydrogen fuel cell, electricity is generated when electrochemical process occurs on combination of hydrogen gas and oxygen.

How do fuel cells convert hydrogen into electricity?

Fuel cells convert hydrogen or a hydrogen-rich fuel and an oxidant (usually pure oxygen or oxygen from air) directly into electricity using a low-temperature electrochemical process.

How do fuel cells work?

Fuel cells are electrochemical devices that convert chemical energy into electrical energy through a controlled redox reaction. They are distinct from batteries in that they require a continuous supply of fuel and oxidant (usually oxygen) to operate, while batteries store their energy internally.

Are hydrogen and fuel cells a viable alternative energy source?

Hydrogen and fuel cells are considered in many countries as an important alternative energy vector and a key technology for future sustainable energy systems in the stationary power, transportation, industrial and residential sectors (European Commission, 2003; US Department of Energy, 2004).
