<P>PROBLEM TO BE SOLVED: To provide a fuel supplying method of a liquid fuel cell in which a minimum limit of an appropriate output of the liquid fuel cell can be grasped accurately and an adding timing of liquid fuel can be grasped accurately in an operation process of the liquid fuel cell. <P>SOLUTION: A calculated comparison value is selected based on each of different electric loading values of loads, its corresponding water solution liquid consumption volume and a high concentration liquid fuel consumption volume. Then, based on a corresponding critical concentration value and a corresponding critical power value, a first curvilinear equation and a second curvilinear equation are decided and the critical concentration value of fuel is calculated by using the first curvilinear equation and the critical power value is calculated based on the second curvilinear equation. When the liquid fuel cell consumes a predetermined volume of fuel, a high concentration liquid fuel and a water solution in fuel consumed by the liquid fuel cell are calculated based on the calculation comparison value and the predetermined volume, and the high concentration liquid fuel and the water solution corresponding to each consumption volume are newly supplied to the fuel. An electric loading value of a load and a power value which the load consumes at this moment are measured, the critical concentration value of the fuel and the critical power value of the load are calculated by using the first curvilinear equation and the second curvilinear equation. Making a judgement on differences between the measured power value and the calculated critical power value, the fuel is supplied. <P>COPYRIGHT: (C)2008,JPO&INPIT |
