<p><P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of reliably determining leak of liquid fuel at startup in a simple structure and restraining a leak volume of liquid fuel. <P>SOLUTION: Before normal power generation of the fuel cell, preliminary power generation steps (steps S1 to S3) of preliminarily making the fuel cell generate power for determining leak of the liquid fuel, and determining steps (steps S2 to S5) of determining existence of leak of liquid fuel based on degrees of fall of pressure P1 of gas produced by the preliminary power generation and exhausted from an anode to a fuel circulation line are performed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
