Embodiment Construction

[0023] The present invention provides a flat-plate direct flame solid oxide fuel cell device and method, and the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] like figure 1 As shown, the lower part of the casing 2 is provided with a partition 7, which divides the casing 2 into an upper non-airtight air chamber and a lower airtight fuel chamber; on the partition 7, a plurality of vertical circular tubes evenly distributed 4. The lower part of the circular tube 4 passes through the partition plate 7 and penetrates into the sealed fuel chamber below the shell 2. The circular tube 4 divides the combustion chamber into evenly arranged fuel paths and air paths; at the bottom of the fuel chamber of the shell 2 A fuel inlet 6 is respectively arranged on both sides, and an air inlet 5 is respectively arranged at the bottom of the air chamber of the casing 2 near the partition 7 and on both sides; A fi...

Abstract

The invention discloses a flat-plate direct flame solid oxide fuel battery device and a method, which belong to the technical field of solid oxide fuel batteries. The device takes a flat-plate solid oxide electrolyte fuel battery as a burning battery; the burning battery is horizontally arranged in a fuel-rich zone above a Hencken burner, wherein the upper side surface is provided with a cathode, the lower side surface is provided with an anode, and the middle part is provided with a solid oxide electrolyte layer; and fuel gas is fed into a fuel inlet, air or oxygen is fed into an air inlet, to form a tubular direct flame fuel battery. The invention can adjust the flame gas components within a larger scope and can keep uniform and flat flame, improve the current density, and can form a large-scale battery pack easily.

Description

technical field [0001] The invention belongs to the technical field of solid oxide fuel cells, and in particular relates to a flat-plate direct flame solid oxide fuel cell device and method. Background technique [0002] Solid Oxide Fuel Cell (SOFC) has many advantages such as high efficiency, high power density, simple structure, and wide fuel adaptability. It has broad application prospects. [0003] Traditional SOFC usually separates the fuel and oxidant gas by two chambers, which can maintain a high chemical potential gradient between the anode and cathode to achieve high power generation efficiency and fuel utilization. However, the double-chamber SOFC seal The quality of the performance directly affects the performance of the battery, especially when the temperature changes, the matching of the expansion coefficient of the sealing material and the battery material is always one of the difficulties in the commercialization of dual-chamber SOFC. Single-chamber SOFC is ...
