All-solid-state electrochemical systems with a composite electrolytes based on calixarene sulfonic acid and phosphotungstic acid used as a proton-conducting membrane and platinised oxide SnO₂(Sb) used as a working electrode material were studied. Variation in the composition of the electrolyte made it possible to improve the characteristics of potentiometric gas sensors for CO at ambient temperature with a short response time (12 s for 1 vol% of CO) and recovery time of 30–35 min. The system with optimal composition is selective to carbon monoxide in air-hydrogen mixture with H₂ concentration comparable to that of CO (up to 1 vol%).

含铂化 SnO2(Sb) 和杯芳烃/磷钨酸复合电解质的固态电位传感器对氢-空气中的 CO 具有选择性

研究了基于杯芳烃磺酸和磷钨酸的复合电解质作为质子传导膜和铂化氧化物 SnO ₂ (Sb) 作为工作电极材料的全固态电化学系统。电解质组成的变化可以改善环境温度下 CO 电位气体传感器的特性，响应时间短（1 vol% CO 为 12 s），恢复时间为 30-35 分钟。具有最佳组成的系统对空气-氢气混合物中的一氧化碳具有选择性，其中 H ₂浓度与 CO 的浓度相当（高达 1 vol%）。
