Unidirectional motion of a proton is completely impossible by the random fluctuation under the thermal equilibrium. It is a breakthrough of science and technology that artificial small perturbation induces a long range unidirectional transport of proton in solids. In this research project, we found a series of materials that exhibit very high proton conductivity in asymmetric nano channel under moderate condition. And we have obtained an evidence of unidirectional proton transfer under small alternate current voltage(~ 0. 1V/mm).

由于热平衡下的随机涨落，质子的单向运动是完全不可能的。人工小扰动诱导质子在固体中长距离单向输运是科学技术的突破。在这个研究项目中，我们发现了一系列在适度条件下在不对称纳米通道中表现出非常高的质子电导率的材料。并且我们获得了小交流电压（~0. 1V/mm）下单向质子转移的证据。
