System and method for heating gas in a continuous focused path within an electric heating unit

An electric heating unit for ammonia dissociation, comprising:

• a housing having a power feed-through, a gas inlet, and a gas outlet;
• a ceramic tube disposed within the housing and fluidly coupled to the gas inlet;
• and
• a heating element having a three-dimensionally (3D) printed lattice structure comprising a series of lattice cells disposed within the housing, the heating element directly coupled to the power feed-through,
• wherein gaseous ammonia enters the electric heating unit via the gas inlet and undergoes a dissociation reaction as the gaseous ammonia travels through the ceramic tube, and
• wherein each lattice cell consists of six vertices, each vertex having an angle of at least 45 degrees.
