Abstract

The present invention provides a capacitor-embedded fuel cell. The capacitor-embedded fuel cell comprises a membrane electrode assembly including a hydrogen ion exchange membrane consisting of a polymeric electrolyte, and a pair of gas diffusion electrodes disposed on upper and lower surfaces of the hydrogen ion exchange membrane, respectively, a pair of separator plates located on outer surfaces of the gas diffusion electrodes and having gas passages formed therein, respectively, and a polymer capacitor located on an outer surface of one of the pair of separator plates while being electrically connected in series to the separator plate.

Description

[0001] related application [0002] This application claims priority from Korean Application No. 2004-39173 filed on May 31, 2004, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a capacitor-embedded fuel cell, and more particularly, to a fuel cell including a capacitor to ensure high energy density. Background technique [0004] In general, a fuel cell is a power source that converts energy generated by means of an electrochemical-chemical reaction between a fuel and an oxidant into electrical energy, and, due to its environmental friendliness and high energy efficiency, has become the mainstay of a new generation of energy supply systems. choice. [0005] In particular, since fuel cells have the advantages of ensuring long-term continuous use and high capacity, it is generally believed that fuel cells will replace conventional storage battery packs used in portable electronic devices such as mobile pho...
