Problems solved by technology

However, judging from the current development situation, previous research tends to design its appearance, and often ignores some application characteristics of the battery itself, such as the carbon deposition problem of the battery, and the price of the fuel that can be used.
In particular, most of the current research uses carbon-containing fuels as fuels, which often lead to battery power drops or even battery ruptures due to carbon deposition, all of which need to be considered

Abstract

The invention relates to a flame fuel battery and preparation method, and new type coalball furnace with said flame fuel battery. The flame fuel battery comprises anode catalyzing layer, anode layer, solid electrolyte layer and cathode layer. The coalball furnace mainly includes outer protecting device and coalball hearth of flame fuel battery. The flame fuel battery in the invention possesses anode catalyzing layer which can anti-carbon to avoid battery to be destroyed by carbon, at the same time, catalyzing layer can reform fuel to increase utilization ratio; using solid oxide fuel battery as hearth, it can generate electricity, but also coalball furnace can work stably; power density and energy density of coalball furnace are high.

Description

technical field [0001] The invention belongs to the field of energy and electric power, and relates to a flame fuel cell, a preparation method thereof, and a novel briquette furnace containing the flame fuel cell. Background technique [0002] As a household heating equipment widely used by people, the briquette stove has been used for many years. It uses the heat of burning briquettes to achieve the effect of heating and heating, which brings convenience to many families. However, because most of the heat of briquette combustion is lost due to not being utilized in time, the energy utilization rate of traditional briquette furnaces is not high. At the same time, some of the synthetic gas produced during the combustion process is often wasted without being burned in time, especially the carbon monoxide in it is not completely reacted but threatens people's health. [0003] Fuel cells can directly convert the chemical energy of fuel into electrical energy without being limit...
