Embodiment 1
[0056] In this embodiment, the present invention provides an ammonia electrolysis hydrogen production device, which includes a hydrogen production component 1, such as figure 2 As shown, specifically:
[0057] A casing 102, along the flow direction of ammonia gas, the casing includes an ammonia distribution chamber 103, a combustion chamber 104 and a reaction chamber 105 in sequence;
[0058] 5 groups of hydrogen production units 101 arranged side by side in the reaction chamber, such as image 3 As shown, the hydrogen production unit 101 includes a battery body with an open end, the battery body has an inner cavity 1015 suitable for inserting an ammonia gas pipe 1011 into the battery body from the open end, and the ammonia gas pipe 1011 penetrates The combustion chamber 104 and the end of the ammonia supply pipe 1011 far away from the inner cavity 1015 communicates with the ammonia distribution chamber 103, so that the ammonia in the ammonia distribution chamber 103 enters the cor...
Embodiment 2
[0073] This embodiment provides a working method of the ammonia electrolysis hydrogen production device provided in Embodiment 1.
[0074] The ammonia gas from the ammonia storage tank 2 enters the ammonia distribution chamber 103 through the ammonia gas inlet 110 along the ammonia gas inlet 110, is distributed into the ammonia supply pipe 1011 of each hydrogen production unit 101, and then enters the inner cavity 1015 of each hydrogen production unit 101. Contact with the anode layer 1013; water flows out of the water tank 4, as the water inlet channel 10 passes through the second heat exchanger 7 to evaporate into water vapor, from the water vapor inlet 114 through the water vapor channel 107 from the water vapor outlet 116 Enter the reaction chamber 105 and contact the cathode layer 1014.
[0075] The following reactions occur in the reaction chamber 105:
[0076] Anode: 2NH 3 +3O 2- =N 2 +3H 2 O+6e -
[0077] Cathode: 3H 2 O+6e - =3H 2 +3O 2- .
[0078] Nitrogen and remaining ammo...
Embodiment 3
[0082] Compared with the embodiment 1, the other structure of this embodiment is completely the same. The only difference is that the ammonia supply pipe 1011 of the hydrogen production unit 101 is filled with an ammonia decomposition catalyst layer 1016, such as Figure 4 As shown, the material of the ammonia decomposition catalyst layer 1016 is Ru simple substance, and the carrier is alumina.
[0083] When this embodiment is working, the ammonia gas enters the ammonia supply pipe 1011 to contact the ammonia decomposition catalyst layer 1016, and part of the ammonia gas is decomposed into hydrogen and nitrogen in advance. After entering the cavity 1015, the hydrogen contacts the anode layer 1013 and contacts the cathode layer. The water vapor ion exchange of 1014, the anode layer 1013 generates water vapor, and the cathode layer 1014 generates hydrogen. The remaining hydrogen in the inner cavity 1015 enters the combustion chamber 104 together with the remaining ammonia, the water...
