The function of the SOFC in six steps:

Step 1

Inside the two seperate gas supply cicuits the gaseous oxygene and hydrogen flow into the gas area and the catalyzer.

Step 2

While getting in contact with the catalyzer the hydrogen molecules (H2) are splitted into two H+ protons. At the same time each hydrogen atom sends out one electron.

Step 3

The electrons move into the anode and cause an electric current. This electric current supplies an electric capacitor with electric power.

Step 4

Respectively four electrons recombine with one hydrogen molecule at the cathode.

Step 5

The now generated oxygene ions have a negative load. They move through the electrolyte (ytrium endowed circon dioxide) to the anode area.

Step 6

The oxygene ions change their electrons with the two protons and oxidize to water.
