为了了解超透膜对含杂质聚变废气中氚回收的适用性，通过室内规模实验考察了氧和碳对Nb和V膜性能的影响。如果膜温度足够高，即高于700K，并且体氧浓度低于1.5at.%，则没有观察到氧气的明显降解。通过将积碳层转化为碳化物层，在高温下操作也可以避免积碳的影响。
In order to understand the applicability of superpermeable membranes for tritium recovery from fusion exhaust gas containing impurities, the influence of oxygen and carbon on the performance of Nb and V membranes was examined by laboratory scale experiments. No significant degradation due to oxygen was observed if the membrane temperature was sufficiently high, i.e. above 700K, and the bulk oxygen concentration was below 1.5at.%. It was also possible to avoid the influence of carbon deposition by the operation at high temperatures through the conversion of carbon deposited layer into carbide layer.
