Abstract:
1. A direct liquid feed fuel cell, comprising: a membrane electrode assembly (MEA) comprising a plurality of unit cells composed of an electrolyte membrane, a plurality of anodes arranged on a first surface of the electrolyte membrane, and a plurality of cathodes arranged on a second surface of the electrolyte membrane and at locations corresponding to the anodes; a current collection plate comprising a plurality of first current collecting portions correspondingly coupled with the anodes; a diffusion plate receiving a liquid fuel supplied through an inlet arranged at a side thereof, the current collection plate being arranged on the diffusion plate; a liquid fuel tank coupled with the inlet and supplying the liquid fuel to the diffusion plate; a plurality of second current collecting portions correspondingly coupled with the cathodes; a porous plate, arranged on the second current collecting portions, and communicating with air; and a conductive portion coupling the first current collecting portions and the second current collecting portions to form an electrical circuit of the unit cells, wherein the diffusion plate comprises a frame projected from an edge of a bottom thereof, and wherein the frame covers sides of the current collection plate, the MEA, and the porous plate.
