Power supply apparatus using fuel cell
First Claim
1. A power supply apparatus using a fuel cell, comprising:
- an adaptor provided with an identification mechanism to identify the type of a secondary cell accommodated therein, the adaptor detachably accommodating the secondary cell and having a certain external shape irrespective of the type of the secondary cell accommodated; and
a charger main body provided with a fuel cell to generate electric power by using fuel supplied from a fuel containing tank, a charging circuit to perform charging by supplying electric power generated by the fuel cell to a secondary cell accommodated in the adaptor, at a charging voltage and a charging current suitable for the type of a secondary cell identified by the identification mechanism, a monitoring circuit to monitor usage state of a portable device, and an output switching circuit that performs switching, depending on a result of monitoring performed by the monitoring circuit, between electric power generated by the fuel cell and electric power outputted by the secondary cell accommodated in the adaptor, and outputs either one of them to the portable device, wherein the charger main body detachably accommodates the adaptor and the fuel containing tank.
