**1.2.1 Molten carbonate fuel cell (MCFC)**

The molten carbonate fuel cell (MCFC) operates at high temperature, which is about 600- 700 °C. It consists of two porous conductive electrodes in contact with an electrolyte of molten carbonate. This type of cell allows the internal reform. The main advantage of the MCFC is its high efficiency (50-60%) without external reformer and metal catalyst, due to the high operating temperature (Farooque & Maru, 2001). This cell is intolerant to sulfur and its launching is slow, these are its main disadvantages.
