Fuel Cells


A fuel cell is an electrochemical device that converts the chemical energy from a fuel directly into electricity and heat.

When hydrogen is supplied as the fuel, it reacts with oxygen to produce electricity, and the only by-products are water and heat. This process is clean, silent, and incredibly efficient. A fuel cell can generate power as long as a fuel source is supplied, unlike a battery which is limited to the stored energy within. Fuels cells are capable of operating on a number of fuels, including natural gas, propane and hydrogen. In these cases, fuel cells do have carbon emissions, which contributes to global climate change, but at a rate significantly less than typical fossil fuel generators or electricity, and they still avoid considerable emissions of other pollutants as well.


Aside from having low or zero emissions, fuel cells are highly efficient and reliable, have great flexibility in terms of installation, operation and scale, and are durable and easy to maintain. As a distributed energy resource, they can contribute to grid resilience and reliability, as well as avoid distribution losses and distribution system investments.
