Abstract
An ammonia manufacturing apparatus of an embodiment includes: an electrochemical reaction cell including: a first reaction tank in which a reduction electrode is arranged and gaseous nitrogen is supplied; a second reaction tank in which an oxidation electrode is arranged and an electrolytic solution containing water or water vapor is supplied; and a diaphragm provided between the first reaction tank and the second reaction tank. In the ammonia manufacturing apparatus of the embodiment, the reduction electrode includes a reduction catalyst that reduces nitrogen to produce ammonia, a porous carbon material that supports the reduction catalyst, and an organic polymer material that binds the porous carbon material. The porous carbon material has pores with a BET average pore size of 1 nm or more and 15 nm or less.
