Advanced Humidity Measurement Solutions for Fuel Cell Efficiency

In the rapidly evolving fuel cell sector, accurate humidity measurement is critical for optimizing performance and durability of systems. As a leading instrument manufacturer, we understand the intricacies involved in developing and sustaining high-performing fuel cells. Our range of humidity and dew-point instruments set the standard for reliability and precision in this challenging field.

The Role of Humidity in Fuel Cell Technology

Fuel cells convert chemical energy into electrical energy through a reaction between hydrogen and oxygen, with water vapor as a byproduct. Controlling the humidity levels within the fuel cell is crucial; too little moisture can dry out the proton exchange membrane, leading to increased resistance and decreased efficiency. Conversely, excess moisture can flood the system, hindering gas flow and reaction rates. Systems are typically optimized in R&D phases, where the lowest uncertainty laboratory measurements are required to test and optimize the final product. Once a working system is designed, more robust and cost-effective measurements are needed.

Precision Humidity Measurement with Rotronic and PST

To address these challenges, we offer a suite of humidity measurement solutions tailored for fuel cell applications. Rotronic, a pioneer in humidity sensing, provides high-accuracy sensors that ensure optimal moisture levels are maintained, enhancing the fuel cell's efficiency and lifespan. These sensors are designed for seamless integration, offering real-time monitoring and control over the critical humidity levels within fuel cells.
