Abstract
An electronic apparatus system of this invention includes an electronic apparatus, and a fuel cell unit which is detachable from the electronic apparatus. The fuel cell unit incorporates a DMFC that can produce electricity by chemical reaction, and a rechargeable secondary battery. The fuel cell unit has a function of informing the electronic apparatus of the states of the DMFC and secondary battery incorporated in it as state information. The electronic apparatus has a function of executing its operation control on the basis of the state information sent from the fuel cell unit.
