Abstract:
1. A direct methanol fuel cell system comprising: a fuel cell; a fuel supply device arranged to supply the fuel cell with an aqueous fuel solution; a first temperature detector arranged to detect first temperature information regarding a temperature of the fuel supplied to the fuel cell; a second temperature detector arranged to detect second temperature information regarding a temperature of the aqueous fuel solution discharged from the fuel cell; an abnormality determination section arranged and programmed to determine an abnormality in the fuel supply device based on a result of comparison between a predetermined value and difference information regarding a difference between the first temperature information and the second temperature information; a concentration detector arranged to detect concentration information regarding a concentration of the aqueous fuel solution; and a concentration adjuster arranged to adjust the concentration of the aqueous fuel solution; wherein the concentration detector performs detection while the concentration adjuster is not in operation.
