Resumen:
CO accompanying the hydrogen produced by methane reforming must be removed when this hydrogen is to be used as feed to a PEM fuel cell,  because it is strongly adsorbed onto the platinum electrode. According to current standards, the maximum amount of CO present must be less than 10 ppm [1]. Among of the major benefits of the preferential oxidation  process (PROX) is its low cost and easy implementation, without involving significant loss of hydrogen [2]. The most interesting catalytic  systems for the PROX reaction are those that combine a noble metal with a second, easily reducible metal [3]. In this work, the objective is to design platinum catalysts, promoted with cobalt, which are suitable for  the PROX reaction and to achieve CO concentrations in the exhaust gas which would then feed a PEM cell, among the above mentioned limits.
