In this tech talk, Steven had the pleasure of discussing about the about Cell Voltage Monitoring (CVM) with Markus Schuster, an expert in electrochemistry at SMART TESTSOLUTIONS.
Learn about Cell Voltage Monitors (CVM)
Steven Oji and Markus Schuster discusses that how CVM measures individual cell voltages within electrochemical stacks like fuel cells or electrolyzers. Markus also provides insights into CVM, its components, functions, applications, and future outlook.
CVM, short for Cell Voltage Monitoring, is explained as a monitoring device used to measure individual cell voltages or cell group voltages within a bipolar electrochemical stack, such as fuel cells or electrolyzers. Markus introduces the components involved, including the CVM system, the Cell Voltage Pickup, and the necessary harness for power supply and data transmission.
The conversation delves into the technical aspects of CVM, including how it measures voltages between bipolar plates and its role in providing real-time data for hundreds of voltages in parallel. The importance of CVM in various industries, including automotive, aviation, trains, trucks, ships, and electrolyzers, highlighting its significance in ensuring the health and efficiency of electrochemical stacks.
Markus addresses the debate around the necessity and cost-effectiveness of CVM by emphasizing its benefits, such as providing deep insights into stack health, detecting critical operational tasks, and preventing irreversible damage, as illustrated by a scenario involving fuel cell cars in extreme temperatures. He also discusses the evolving landscape of CVM, with advancements leading to more modular designs, lower costs, and broader applications beyond research and development. The conversation concludes with a discussion on the future outlook for CVM, with expectations of further integration into serious applications and ongoing advancements in technology and cost reduction.
