FUEL CELLS.
Abstract
Mass transfer in solid metal electrodes was studied intensively with a view to defining the total transfer process so as to permit a reasonably accurate calculation of the resistances to mass transfer of the several steps. A model for the transfer process is presented and the several steps discussed. It appears that mass transfer from the bulk gas cannot be calculated until more is known about the absorption processes occurring at the gas-metal interface. Methods of measuring gas solubility and diffusivity in fuel cell electrolytes are dascussed and the results of preliminary measurements presented. A polarographic method appears satisfactory for measuring the diffusivity of oxygen in KOH solutions, and a chromatographic method appears suitable for determining gas solubility. (Author)
