SENSOR-LESS METHOD AND APPARATUS FOR CONTROLLING FUEL CONCENTRATION OF LIQUID FUEL CELL, LIQUID FUEL CELL APPARATUS USING THE SAME

摘要

A method for controlling the fuel concentration of s liquid fuel cell is provided to save the electricity used on system operation by making a simple and compact fuel cell system by using a sensor. A method for controlling the fuel concentration of s liquid fuel cell comprises a step of measuring the fuel consumption or consumption velocity of a liquid type fuel battery while changing the operation condition, and determining the fuel consumption or consumption velocity of the fuel; and a step of controlling the fuel concentration of a liquid type fuel battery by controlling the fuel supply amount or the feed rate supplied to the fuel battery corresponding to the fuel consumption or consumption velocity of the fuel.
