The function of the MCFC in seven steps:

Step 1

There are two seperate gas supply systems. At the cahode area there is oxygene and carbon dioxide. At the anode area there is hydrogen. The gas flow touches the catalyzer.

Step 2

The hydrogen molecules are splitted into two H+ protons at the catalyzer. Each hydrogen atom sets one electron free.

Step 3

The electrons move from the anode to the cathode and cause an electric current. This electric current supplies an electric capacitor with electriv 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 and react with carbon dioxide into carbonate ions.

Step 6

The negative loaded carbonate ions move through the electrolyte (molten carbonate) into the direction of the positive loaded protons at the anode side.

Step 7

The carbonate ions change their negative loads with two protons and oxidize with them to water. Because of the split off of the oxygene ions from the carbonate, carbon dioxide is generated again.
