System for decomposing ammonia and method of decomposing ammonia

A method of decomposing ammonia, the method comprising:

• receiving an internal temperature information of a cracker for decomposing ammonia to generate hydrogen from a sensor for sensing an internal temperature of the cracker;
• receiving a residual ammonia information in the cracker;
• and
• controlling an operation of a bypass line based on at least one of the temperature information and the residual ammonia information, the bypass line connecting a pipe that connects the cracker and a fuel cell with a pipe connecting the fuel cell and a heater.

A system for decomposing ammonia, the system comprising:

• a cracker decomposing an ammonia feed to generate a decomposition product comprising hydrogen, nitrogen, and residual ammonia and feeding the decomposition product to an absorber;
• the absorber for absorbing the residual ammonia from the decomposition product and feeding the remaining mixture of hydrogen, and nitrogen to a fuel cell;
• the fuel cell reacting at least a portion of the hydrogen received from the absorber to generate power;
• a bypass line connecting a pipe that connects the cracker and the fuel cell with a pipe connecting the fuel cell and the heater;
• a sensor for sensing an internal temperature of the cracker and transmitting the internal temperature to a controller;
• and
• the controller receiving the internal temperature of the cracker from the sensor, and controlling an operation of the bypass line based on the internal temperature received from the sensor.
