Abstract

The invention belongs to the technical field of ammonia decomposition, in particular to an ammonia fuel cell system and an electric device. The ammonia fuel cell system comprises an ammonia decomposition reaction device, a heating device, a hydrogen fuel cell, a DC/DC converter and an inverter which are connected in sequence, a battery pack and a heat exchanger. The ammonia fuel cell system can run stably for a long time and form recycling utilization and have the advantages of high flexibility, low energy consumption and high system utilization rate. The heat exchanger of the system can make the energy produced by ammonia decomposition preheat ammonia gas and realize recovery and utilization of waste heat. The battery pack can make the battery pack respond quickly and output stably and can deal with acceleration and deceleration of the electric device quickly so as to improve the stability of system operation and can transmit the electric energy generated by the hydrogen fuel cell or the electric energy in the battery pack to the outside. The battery pack or the heating device of the system can provide energy for the ammonia decomposition reaction device without external energy for the ammonia decomposition reaction device.

Description

technical field [0001] The invention belongs to the technical field of ammonia decomposition, and in particular relates to an ammonia fuel cell system and an electric device. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect and has high efficiency. In addition, fuel cells and oxygen are used as raw materials, and there are no mechanical transmission parts, no noise pollution, and less harmful gas emissions. It can be seen that from the perspective of saving energy and protecting the ecological environment, fuel cells have good development prospects. [0003] A f...
