What is a Fuel Cell?

Fuel Cells are energy conversion devices set to replace combustion engines and compliment batteries in a number of applications. They convert the chemical energy contained in fuels, into electrical energy (electricity), with heat and water generated as by-products. Fuel cells continue to generate electricity for as long as a fuel is supplied, similar to traditional engines. However unlike engines, where fuels are burnt to convert chemical energy into kinetic energy, fuel cells convert fuels directly into electricity via an electrochemical process that does not require combustion. This process enables fuel cells to be more efficient at creating electricity than engines which have to go through an additional step to convert the kinetic energy into electrical energy.

These technologies offer a combination of benefits that can:

• Lower your carbon footprint
• Reduce noise and air pollution
• Reduce fuel bills – through the use of more efficient technology
• Utlise renewable fuels produced onsite.
• Generate heat and power onsite
• Improve environmental credentials and corporate social responsibility
• Potential long-term money savings
• Earn ROQ’s

All fuel cells contain either solid or liquid Electrolytes sandwiched between two electrodes. There are a number of different Types of Fuel Cells, and these are characterised by their particular electrolyte. Different types of fuel cells operate at different temperatures and on a variety of fuels, including both gaseous fuels such as hydrogen, natural gas, propane and biogases, to liquid fuels such as methanol and ethanol. Low temperature fuel cells require pure hydrogen, whereas higher temperature fuel cells can operate directly on hydrocarbon fuels such as natural gas. There are several main types of fuel cells (see LHS), each more suitable for particular applications.
