A direct methanol fuel cell (DMFC) is especially expected as a new, high density energy source for mobile usage; however its power density weakness becomes problematic. As a result, the size of a portable electronic equipment using DMFC is far larger than that of the one which uses another battery. Additionally, steady power supply control is difficult, because output power of the DMFC is changed by the environment etc. First of all, this paper presents pulse charge control system that is a new control system applied to a mobile device, which uses the DMFC and an electric double layer capacitor (EDLC), and shows the new passive heat control and the experiment result.
