| Research Abstract |
Oxygen-permselective membranes for the air battery of next generation were studied from the view point of facilitated transport of oxygen. Oxygen permeation through membranes was measured electrochemically with a half cell by detecting the reduction current of the permeated oxygen on a carbon electrode. This method was especially effective for the facilitated oxygen transport thorugh the membranes containing cobaltporphyrin as an oxygen-specific fixed carrier. The facilitated oxygen transport was also observed for a liquid membrane containing bovine hemoglobin. Chemically specific surface diffusion of oxygen was successfully realized on a porous glass membrane modified on its pore surface with cobaltporphyrin. The membrane displayd both permselectivity for oxygen and high permeability. The enhanced and specific diffusion of oxygen was analyzed with a parallel model involving surface diffusion of oxygen. Barrier property against water vapor was given to the membranes by coating a thin layr of fluoro-polymer or by polyvinyliden chloride polymer. The facilitated factor of oxygen was augmented to 80 for these membranes.
