Introduction
A fuel cell is an electrochemical cell that produces power through a reaction, triggered in the presence of an electrolyte, between the fuel (on the anode side) and an oxidant (on the cathode side). The reactants flow into the cell, and the reaction products flow out of it, while the electrolyte remains within it. Currently a couple of fuel cells are available, which can be allocated to different fuel cell families as shown in the table below.
| Type | Efficiency | Operating temperature |
|---|---|---|
| Solid Oxide | 45-65% | 800°C |
| Molten Carbonate | 50% | 650°C |
| Phosphoric Acid | 40% | 200°C |
| Alkaline | 50-60% | 80°C |
| Direct Methanol | 40% | 80°C |
| Polymer (PEM) | 40% | 50°C |
