Sulfonated polystyrene-co-acrylic acid membranes modified by transmembrane reduction of platinum

The transmembrane reduction, also known as Takenaka-Torikai method, was used as a simplified process to obtain metal-polymer composite membranes useful in fuel cells. The method involves a device consisting of a cell with two separated compartments, divided by the ion exchange membrane to be modified. Once the reductor from one compartment diffuses through the membrane, reach the precursor solution, on the other compartment, reducing it to...
