Abstract

This invention provides a fuel battery unit cell, which can realize a size reduction and a cost reduction, a fuel battery unit cell array, a fuel battery module, and a fuel battery system. The fuel battery unit cell has a pin structure comprising a fuel electrode (11) formed of a p-type semiconductor, an oxygen electrode (13) formed of an n-type semiconductor, and an intermediate layer (12) interposed between the fuel electrode (11) and the oxygen electrode (13) and formed of an authentic semiconductor. The fuel electrode (11) and the oxygen electrode (13) are porous and permeable to a fluid. A metal-base catalyst layer is provided on the inner surface of pores in the porous part. The intermediate layer (12) is porous and permeable to a hydrogen ion produced in the fuel electrode (11) and is impermeable to electrons. A hydrogen-containing fuel is supplied on the surface of the fuel electrode (11), and an oxygen-containing oxidizing fluid is supplied on the surface of the oxygen electrode (13). Connecting terminals electrically connected respectively to the fuel electrode (11) and the oxygen electrode (13) are provided.

Description

technical field [0001] The present invention relates to a fuel cell unit cell having a pin structure or a pn structure, a fuel cell module, and a fuel cell system, and more specifically, relates to a metal-based catalyst or an oxide-based catalyst capable of effectively exerting the catalytic action including platinum and ruthenium , Fuel cell cells, fuel cell cell arrays, fuel cell modules and fuel cell systems for small fuel cells. Background technique [0002] Fuel cells mainly use fuel gas as fuel, and generate electricity by using hydrogen-containing gases such as hydrogen and methane or liquids such as methanol to react the fuel gas or liquid fuel with oxygen in the air. At this time, the discharge is mainly water, and harmful discharge such as carbon dioxide and carbon monoxide gas is extremely small, so it has attracted special attention in recent years as an environmentally friendly energy generation mechanism. In addition, unlike engines, turbines, etc., fuel cell...
