An electric power supply apparatus and a portable electronic device equipped with the electric power supply apparatus are disclosed. The electric power supply apparatus can include: a replaceable cartridge that supplies hydrogen or electrical power; a housing that forms a cavity, in which the cartridge may be inserted; a stack connected with the cartridge and configured, if the cartridge is supplying hydrogen, to receive the hydrogen from the cartridge and generate electrical power; and a circuit unit electrically connected with the cartridge and the stack that determines the type of the cartridge and supplies electrical power to the electronic device. With certain embodiments of the invention, a device can be recharged using replaceable cartridges. Also, various types of cartridges can be used in a single system, allowing a higher level of compatibility.
