Fuel Cell System Design

Operating Principle

Fuel cell systems have three main sections:

1. The fuel processing section, is where a steam reformer and a shift converter or reactor, are used to convert fuel into the hydrogen-rich gas required to sustain an electrochemical reaction in the power section. The steam reformer converts the fuel gas (e.g., methane) to hydrogen (H2) and carbon monoxide (CO) over a nickel catalyst by the reaction:

In some fuel cell systems, in the reactor, the CO is reacted with steam over an iron-chrome catalyst at a lower temperature to produce more hydrogen and reduce the CO content to less than 1 ppm:

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
