gas concentration cell meaning in Chinese

气体浓差电池

As a comparison , ba1 . 03ce0 . 8gd0 . 2o3 - was synthesized by sol - gel method . among these samples , nonstoichiometric samples were synthesized for the first time . the research work involved : the crystal phase of the sinters were determined by xrd ; ionic conduction under different experimental atmospheres was measured by gas concentration cells ; performances of hydrogen - air fuel cells with the sinters as electrolytes and porous pt as electrodes were measured
用粉末x射线衍射仪鉴定它们的结晶相；在( 600 1000 )范围内，以烧结体作为电解质隔膜，多孔性pt黑为正、负电极， pt - rh合金网为集电极，分别组成氢浓差电池、氧浓差电池及氢?空气燃料电池并测定了它们的性能，研究了不同气氛下样品的离子导电特性及影响燃料电池性能的因素。
