Electrochemical module with stacked elements and gas flow mechanism
The patent US11996592B2 describes an innovative electrochemical module designed to enhance the efficiency and functionality of electrochemical reactions. The module features a stack of electrochemical elements, each comprising an electrolyte layer flanked by electrode and counter electrode layers. These elements are arranged in a specific stacking direction and are sealed with an annular portion that allows for the flow of a first gas, which can be either a reducing or oxidative component. The module includes a clamping mechanism that secures the stack, a flowing pipe for gas supply and discharge, and a pressing mechanism that ensures consistent pressure on the annular sealing portion. Notably, the design incorporates a dual screw mechanism to facilitate the pressing action, with provisions for thermal expansion and electrical insulation.
Additionally, the patent outlines various configurations and enhancements to the electrochemical module, such as the inclusion of gas-permeable substrates, internal passages for gas flow, and multiple sealing portions to maintain gas integrity. The module can be integrated into broader electrochemical devices, including fuel converters and power converters, which can either supply or extract energy. Furthermore, the patent describes an energy system that utilizes waste heat from the electrochemical device, promoting energy efficiency and sustainability. Overall, the claims present a comprehensive approach to improving the performance and reliability of electrochemical systems, with potential applications in energy generation and conversion technologies.
