| How The PureCell® System Works
(Click to download a pdf version of "How It Works")
(1) FUEL PROCESSOR
The Fuel Processor (reformer) reforms the fuel (natural gas) to hydrogen gas to feed the Fuel Cell Stack. |
(2) FUEL CELL STACK
Hydrogen gas and air are combined in an electrochemical process that produces Direct Current (DC) power, pure water and heat. The byproduct water is utilized in the operation of the power plant. The usable heat is available for meeting other facility energy requirements (e.g., hot water, space heating, air conditioning and cooling). |
(3) POWER CONDITIONER
The DC power provided by the Fuel Cell Stack is conditioned to provide high quality Alternating Current (AC) power output. | |

How A Fuel Cell Works
(1) ANODE
As hydrogen flows into the fuel cell anode, a catalyst layer on the anode helps to separate the hydrogen atoms into protons (hydrogen ions) and electrons.
(2) ELECTROLYTE
The electrolyte in the center allows only the protons to pass through the electrolyte to the cathode side of the fuel cell.
(3) EXTERNAL CIRCUIT
The electrons cannot pass through this electrolyte and, therefore, must flow through an external circuit in the form of electric current. This current can power an electric load.
(4) CATHODE
As oxygen flows into the fuel cell cathode, another catalyst layer helps the oxygen, protons, and electrons combine to produce pure water and heat.
(5) FUEL CELL STACK
Individual fuel cells can be combined into a Fuel Cell “Stack” to increase the total electrical output. |
