Abstract
The body of an electronic apparatus houses a DMFC unit which produces energy by causing methanol supplied as fuel to react with oxygen. The body further houses a cartridge fuel tank which holds methanol, fuel for the DMFC unit. Furthermore, on the body, there is provided an attachment (connector unit) to which an external fuel tank unit holding a large amount of methanol, fuel for the DMFC unit, can be connected. In the external fuel tank unit, two fuel tanks of the same shape are provided so as to be installed and removed freely.
