Title:
燃料電池システム
Document Type and Number:
Japanese Patent JP6927071
Kind Code:
B2
Abstract:
To provide a fuel cell system capable of grasping the drainage volume of a fuel cell appropriately.SOLUTION: A fuel cell system has: a fuel cell; a pressure accumulator of fuel gas; an injector for injecting the fuel gas flowing in from the pressure accumulator; a recycling path through which fuel off-gas flows; an ejector for blending the fuel off-gas to the fuel gas and introducing to an anode of the fuel cell; a detector for detecting the current value of the fuel cell; and a control device for controlling the one time injection time and injection amount of the injector. The control device estimates pressure loss from a water content and the current value on the basis of correlation of the anode side water content of the fuel cell, pressure loss in the recycling path, and the current value, estimates the flow from the estimated pressure loss on the basis of the correlation of the pressure loss in the recycling path and the flow of the fuel off-gas, calculates an impulse of the fuel gas introduced to the fuel cell from the ejector and the fuel off-gas on the basis of the flow, the injection amount, and the injection time, and then calculates drainage volume of the fuel cell on the anode side on the basis of the impulse and the water content.SELECTED DRAWING: Figure 2
