An autothermal ammonia reactor includes a chamber, a hydrogen-separation membrane within the chamber, and an ammonia decomposition catalyst. The chamber receives ammonia and air. The chamber including a combustion zone, a catalytic zone, and a hydrogen zone. The catalytic zone is in thermal communication with the combustion zone. The chamber directs the air and a portion of the ammonia from the fluid inlet to the combustion zone to allow the air and ammonia to exothermically react to generate thermal energy. The chamber directs another portion of the ammonia into the catalytic zone to decompose into hydrogen and nitrogen as the ammonia is exposed to the thermal energy from the combustion zone and contacts the catalyst. The chamber directs the hydrogen from the catalytic zone, through a surface of the hydrogen-separation membrane, to the hydrogen zone to allow the hydrogen to exit the chamber through the fluid outlet.
