Abstract

Provided is a fuel tank for a fuel cell and fuel cell system capable of supplying fuel in any direction of installment and processing exhausted substance. The fuel tank is constructed so as to press the fuel (111) to be supplied to the fuel cell main body (200) by pressing a separation plate (130) moving through the inside of a casing (140) by the exhausted substance (123) exhausted from the fuel cell main body. By the above, the fuel can be stably supplied to the fuel cell main body whether the fuel tank for the fuel cell (100) and the fuel cell system (30) are installed in any direction. In addition, since the exhausted substance is utilized for pressing the separation plate, the exhausted substance can be processed.

Description

technical field [0001] The present invention relates to a fuel cell fuel tank connected to a fuel cell body that directly supplies an organic fuel such as methanol to an anode to generate electricity, and a fuel cell system including the fuel cell fuel tank. Background technique [0002] In recent years, fuel cell systems have attracted attention as a next-generation clean and efficient energy source. Among them, a solid polymer electrolyte fuel cell (PEFC: Polymer Electrolyte Fuel Cell) in which an anode and a cathode are sandwiched between a solid polymer electrolyte is attracting attention especially as a power source for electric vehicles and a distributed power source for household use. Among the above-mentioned solid polymer electrolyte fuel cells, fuel cells that directly supply organic fuels such as methanol or dimethyl ether to the anode to generate electricity, such as direct methanol fuel cells (DMFC: Direct Methanol Fuel Cell) do not need to use organic fuel such...
