The invention is directed to developing a technique to estimate the remaining time for generating electrical power, which is applicable to small fuel cells used as a power supply in small electronic devices such as mobile phones or portable computers. In a fuel cell system comprising a fuel cell, a fuel used directly or indirectly for the fuel cell, and a module with internal electrical or physical properties that change as the fuel is used, the present invention is characterized by a method for estimating the remaining time in which the fuel or hydrogen created from the fuel can be provided to the fuel cell, where providing a plurality of electrodes inside the module, measuring electrical or physical properties of the space between at least two of said electrodes, and estimating the remaining time based on the measurement results. |
