Titanium suboxides as a catalyst support for PEMFC
Original language description
Subject of this study was preparation of the platinum catalysts supported by the Magneli phases. Chemical reduction of the platinum salt by formaldehyde in water and by ethylene glycol with and without poly(vinylpyrrolidone) was tested. Prepared catalysts were characterized using cyclic voltammetry and linear sweep voltammetry both for hydrogen oxidation and oxygen reduction. SEM was used to characterize samples morphology. Selected catalysts were characterized in the laboratory fuel cell. Results showthat in the system under study either small nanoparticles with good distribution but small loading or large loading with larger clusters of nanoparticles can be obtained at the present state of knowledge. To obtain good distribution, high loading and small nanoparticles, support specific surface area higher than 100 m2 g 1 represents a necessary precondition. It can be therefore concluded, that the Magneli phases will not represent suitable replacement for carbon black in fuel cell appli
