ABSTRACT:
A high capacity micro fuel cell system for supplying power to a portable device. A fuel supply includes a fuel inlet formed at one side of a substrate and a gas outlet formed at the other side of the substrate. A pair of cell units are disposed at opposed sides of the substrate of the fuel supply, and each of the cell units includes catalyst layers and an electrolyte layer between the catalyst layers to generate current with fuel. Outer substrates are disposed at outer sides of the cell units, each of the substrates having through holes formed therein to define at least one oxygen supply for supplying oxygen to the electrolyte layers of the cell units. A holder integrally assembles the fuel supply, the cell units and the oxygen supply. The fuel cell system supplies high-capacity power to power supplies of portable electronic devices and can be mass-produced at low costs.
