PREPARATION AND PROPERTIES OF PALLADIUM DEPOSITS ON CARBON CLOTH

The possibilities of palladium deposition on carbon cloth (type ULSh) by electrodeposition and impregnation were investigated; the character istics of the resulting Pd/C electrodes were determined. Hydrogen adso rption and absorption were studied by using copper adatoms; the amount s of hydrogen dissolved in the alpha-phase of Pd(H) were studied as a function of potential; the isotherm of hydrogen adsorption was calcula ted. A correlation was found to exist between the hydrogen concentrati on in the alpha-phase of Pd(H) and the degree of dispersion of the pal ladium.
