Abstract At present, coal, petroleum, natural gas is the main energy used by people。 However, these resources are not inexhaustible。one day ,they will run out。 Now the energy use efficiency of power generation equipment is very low。And it is easy to  cause environmental pollution。 Therefore, development and utilization of environmental pollution is low, high energy utilization rate of resources is very important for our country and even the world。 Nowadays, the fuel cell as an efficient, clean, efficient energy security,has already into the public view。And the tube type solid fuel cell is more widely used because of its high sealing performance and low cost。Influence on the performance of tubular solid oxide fuel cell anode current collector is mainly studied in this paper。

The first chapter introduces the research background and development process of fuel cell。 Secondly, it's simply introduct about the basic principle of fuel cell and its working process。 At the same time for fuel cell types and their advantages and disadvantages were system analysis。 Then, this paper introduces the solid oxide basic principle and advantages。 In the second chapter, the anode supported tubular solid oxide fuel cell is introduced, including the geometric structure, the gas transportation control equation, the conductive

control equation and the electrochemical equation。

In the third chapter, the inner diameter and the thickness of cathode are analyzed:effect of anode current collector width on the performance of the battery。 The results show that when the tube diameter is certain, with the increase of the width of the collecting anode member, corresponding to the output current also increased,  but the output current growth rate decreases。 When the cathode thickness is certain, with the increase of the width of the collecting anode member, current output also increased, but the output current growth rate decreases。

The conclusion part makes a summary of this paper。

Keywords: fuel cell ;SOFC; Anode Channel;Anode current collector position
