说明

General description

We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Phosphoric acid-doped polybenzimidazole (PBI) membranes offer a cleaner path to energy by enabling high-temperature fuel cells that efficiently convert hydrogen into electricity with low emissions. Their durability and proton conductivity make them ideal for sustainable power systems. Click here for more information.

Application

利用增强SAP的离子层和CNT掺杂进行多点压力测量的全新电阻传感器网络：本文展示了磷酸溶液在为各种技术应用（从医疗保健到消费电子产品）创建灵敏且精确的压力传感器中的作用（Fan等人，2024年）。

Other Notes
