A fuel cell is an ammonia fuel cell using an ammonia-containing fuel. A catalyst used for an anode of the fuel cell is a ruthenium complex having two first ligands and one second ligand, and the first ligand is pyridine or a condensed cyclic pyridine compound with or without a substituent, and the second ligand is 2,2'-bipyridyl-6,6&#x2032;-dicarboxylic acid with or without a substituent on a pyridine ring.
