Abstract

The invention relates to an application of ammonia to an SOFC battery and an application apparatus of the application. The application is characterized by comprising a step 1 of ammonia gas heating and a step 2 of ammonia gas decomposition. A heating and decomposition apparatus comprises a first pressure-reducing valve, a first solenoid valve, a high-temperature-exhaust-gas discharging cylinder, a heat exchange chamber, an annular high-temperature-resistant stainless-steel coil pipe, a temperature inductor, a safety vent valve, a gas-mixing chamber, a decomposition chamber, a spiral airway structure, gas dispersing and burning nozzles with igniters, a second solenoid valve, a second pressure-reducing valve, a third solenoid valve, a fourth solenoid valve, and a drying and purifying devices. The application has advantages that ammonia is free of carbon and can be used as fuel, and therefore, the 'carbon poisoning' phenomenon of an SOFC catalyst is completely overcome; during a hydrogen production process through ammonia gas decomposition, no vapor is required, so that requirements for devices and water resources are reduced; and fuel gas heating is adopted, so that the SOFC battery can be applied to a mobile device. Waste heat is utilized, and energy is effectively saved.

Description

Technical field

[0001] The invention relates to an application of ammonia in a SOFC battery and its application device. Background technique

[0002] Now that fossil fuels are increasingly depleted, people are working hard to develop new energy sources. Fuel cells can use energy more efficiently without polluting the environment. Fuel cells are a new ideal power generation technology.

[0003] The fuel cell is a kind of electrochemical reaction mainly through oxygen or other oxidants and fuel. The fuel cell is a battery that converts the chemical energy in the fuel into electrical energy. In the fuel cell, the fuel and air are respectively sent to the anode and cathode of the fuel cell. Electricity will be produced. At present, there are many different technical solutions for fuel cell power generation, such as alkaline fuel cell (AFC), proton exchange membrane fuel cell (PEMFC), phosphoric acid fuel cell (PAFC), and molten carbonate fuel cell (MCFC). And solid oxide fuel cells (...
