Abstract. The structure of commutative Moufang algebras is studied. We show in particular that the set of idempotent elements is contained in the center of the algebra thus it has a boolean ring structure. Simple and semi-simple commutative Moufang algebras are associative and the associator (x,y,z) is always in the nilradical.Palabras claves.
