A fuel cell is the most efficient way of converting fuel energy into electricity. It doesn’t matter whether the fuel is natural gas or hydrogen. Fuel cells convert fuel and air directly into power and heat in a chemical reaction. This makes the process efficient, reliable and quiet.

How a fuel cell works

Fuel passes over the anode side and air passes over the cathode. Sandwiched between the anode and cathode is the very thin, electrolyte layer. An external circuit connects the anode to the cathode and provides the mechanism to take power from the fuel cell to power electrical devices.

A single cell can power a low-energy light bulb. Approximately 100 cells are combined to create a stack. One stack could supply up to 90% of a home’s electricity needs and all of its hot-water.

The Steel Cell is completely scalable, for example 200 stacks can supply a large office, apartment block or supermarket.
