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.

从促进氧传递的角度研究了下一代空气电池用氧选择透过膜。通过检测渗透的氧在碳电极上的还原电流，用半电池电化学地测量通过膜的氧渗透。该方法对以钴卟啉为氧特异性固定载体的膜的氧传递有明显的促进作用。对于含牛血红蛋白的液膜也观察到了促进的氧传输。用钴卟啉修饰多孔玻璃膜的孔表面，成功地实现了氧的化学专一性表面扩散。该膜对氧具有选择透过性，同时具有较高的渗透性。氧的增强和特定的扩散进行了分析，与一个平行的模型，包括表面扩散的氧。通过涂覆一层含氟聚合物或聚偏氯乙烯聚合物，使膜具有对水蒸气的阻隔性能。这些膜的氧促进因子提高到80。
