ABSTRACT

Fossil fuel is currently the predominant energy source. In all likelihood, fossil fuel will remain the dominant energy source for the remainder of this century. Consuming the depleting energy source in an economic and environmentally friendly way is of tremendous importance for a sustainable society. Solid oxide fuel cell (SOFC) is a device that converts chemical energy into electricity by means of an electrochemical (EC) process and offers great potential for high efficiency and environmentally benign electric energy generation. The high operating temperature of SOFC is advantageous for fuel flexibility and high efficiency as CO can be directly used as fuel. It also offers the possibility of adding a bottoming thermal engine cycle and/or heat cogeneration for even higher efficiency. Consequently, SOFC is attracting increasing attention in recent years [1].
