And as fossil fuels (coal, petroleum, natural gas) the increasing depletion of resources, development and utilization of renewable energy systems, adjustment of energy structure of human society has become an urgent need to be addressed. Fuel cell is widely recognized as efficient, convenient and environmentally sound green energy devices. Fuel cells with high efficiency, environmental friendly, safety, high reliability and so on, can also solve the energy and green the worlds two major problems in the future hydrogen economy era, the core of the emerging industry chain, it will reduce dependence on oil imports to protect the national energy safety and reduce the greenhouse effect, to improve the quality of the environment. In this paper, the basic concept and basic working principle of fuel cells are specifically described, The efficiency and the methods to increase efficiency of the fuel cells are discussed through quantitative. Fuel cells had the unusual characteristic: Its power efficiency is more than 60%, you can repair and maintain it without unloading, but in addition to the low ratio of carbon oxide emissions outside, virtually no other harmful emissions. This article describes the four kinds of main fuel cells divided in accordance with the temperature (PEMFC, PAFC, MCFC and SOFC) performance, focusing on high-temperature solid oxide fuel cell (SOFC) application and its developmen
