The procedure is for obtaining covering using the technique of automatic aerography employs suspensions of nanometric powder or substances obtained by sun-gel. The nanometric powder is prepared chemically and then the suspension is prepared from the nano-particulated powder. Then covering is carried out by automatic aerography. This procedure enables catalytic coverings to be made for the development of electrodes for fuel batteries. For the aerography, an aerograph (1) is used incorporated by a rail (2) which moves following a triangular wave activated by a wave generator (5) assisted by a compressor (4) which generates a projection (5) of Pt on a substrate.

El procedimiento parte de la preparación del polvo nanométrico mediante una vía química, seguidamente se procede a la preparación de la suspensión o tinta a partir del polvo nanoparticulado. A continuación se realiza el recubrimiento por aerografiado automático. Este procedimiento permite la obtención de capas o recubrimientos catalíticos para el desarrollo de electrodos para pilas de combustible mediante esta técnica de aerografiado automático. Para el aerografiado se utiliza un aerógrafo (1) incorporado a un raíl (2) que se mueve siguiendo una onda triangular, activada mediante un generador de ondas (3), y asistido por un compresor (4), para generar una proyección (5) de Pt sobre un sustrato de C.
