FUEL CELL SYSTEM AND CONTROL METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To suppress false detection as a high value for a pressure value in a tank.SOLUTION: A fuel cell system includes: a fuel cell; a tank for storing gas to be used for the fuel cell; a first pressure sensor for measuring charging pressure to be pressure in gas charging to a charging pipe for charging gas in the tank; a second pressure sensor for measuring supply pipe pressure to be pressure when starting the fuel cell in a supply pipe for supplying gas from the tank to the fuel cell; a temperature sensor for measuring an inner temperature of the tank; and a control unit for finding out an estimated pressure value of the supply pipe pressure on the basis of a first pressure value indicating the charging pressure when starting the fuel cell, the inner temperature when the first pressure value is measured and the inner temperature when the supply pipe pressure is measured and detecting a lower value out of the estimated pressure value and the second pressure value indicating the supply pipe pressure as supply pipe pressure.SELECTED DRAWING: Figure 3
