METHOD OF LARGE POWEWR SOLID OXIDE FUEL CELL

摘要

PURPOSE: A manufacturing method of unit cells for high power solid oxide fuel cell is provided to manufacture the unit cells by controlling the fine structures only by controlling the grain size of an YSZ ion conductor without using a porosity aid. CONSTITUTION: A unit cell for high power solid oxide fuel cell comprises a fuel anode support layer(11), a fuel anode reactive layer(12), a transmitted layer(13), and a cathode layer(14). In the manufacturing method of the unit cells for high power solid oxide fuel cell, the fuel anode reactive layer is manufactured by mixing NiO powder with 2 different types of YSZ powder. The NiO powder has a size of 2-3 microns. The YZS powder is used by mixing 0.2-0.5 microns size of the first powder with the second powder. The YZS powder is obtained by mixing the first powder with the second powder with a weight ratio of 1:1.
