Fuel cell system

Abstract

A fuel cell system includes a fuel cell body to generate electrical energy using a reaction of hydrogen and oxygen; a reformer to generate a reformed gas containing hydrogen by reforming fuel and to supply the reformed gas to the fuel cell body; a fuel tank to store the fuel in a partially liquefied state and to supply the fuel to the reformer; a case to encase the fuel cell body and the reformer; and a refrigeration unit attached to the case to store ambient air of the fuel tank, the ambient air of the fuel tank being cooled by latent heat of vaporization of the fuel.

Description

technical field The invention relates to a fuel cell system. More specifically, the present invention relates to a fuel cell system using a liquefied gaseous fuel such as butane. Pursuant to 35 U.S.C. §119, this application claims priority to an earlier application entitled "FULL CELL SYSTEM" with Serial No. 10-2006-0019479 filed with the Korean Intellectual Property Office on February 28, 2006, which Incorporated in this application by reference. Background technique A fuel cell is a power generator that uses fuel and oxidant gas to generate electricity. In general, fuel cells can be classified into polymer electrolyte membrane fuel cells and direct oxidation membrane fuel cells. A system employing a polymer electrolyte membrane fuel cell includes a stack, a reformer, a fuel supply section, and an oxidant gas supply section. The stack includes a plurality of fuel cells arranged continuously therein, the reformer generates reformed gas by reforming fuel, the fuel sup...

AI Technical Summary

Problems solved by technology

Therefore, the fuel tank cannot supply enough fuel to the reformer due to the reduced amount of vaporized liquefied gaseous fuel
