In this Hyfindr Tech Talk, we discuss Cell degradation and aging. Degradation refers to the decline in performance of electrolyzer or fuel cell components, such as membranes, electrodes, and seals, leading to reduced hydrogen production. Aging encompasses various processes, including corrosion, mechanical stress, and thermal damage, which compromise efficiency over time. Tools like DiLiCo Engineering’s CureTemp sensors analyze internal conditions, mapping current and temperature distribution to detect inefficiencies or damage. By optimizing operating parameters and detecting issues early, users can improve performance and longevity, yielding significant financial gains, such as €800,000 additional income from a 1% efficiency boost in hydrogen production.

Executive Summary of Tech Talk Script:
In this Hyfindr Tech Talk, we discuss Cell degradation and aging. Cell degradation refers to the decline in performance of components within an electrolyzer cell, resulting in reduced hydrogen production over time. Closely related is cell aging, which describes the natural wear and tear due to prolonged use. Factors such as mechanical stress, corrosion, high temperature, and pressure differences significantly influence these processes.
Maik Heuer, a Ph.D. engineer and founder of DiLiCo Engineering, shares insights on monitoring and addressing cell aging using innovative sensor technology. The DiLiCo CureTemp system is designed to measure current and temperature across a cell’s surface. Installed between cell components, it provides real-time, granular data about performance variations within different segments of the cell. This technology helps identify issues like hotspots, poor flow conditions, or material stress, all of which contribute to degradation.
A vivid analogy compares the surface of a cell’s catalyst to crumbs on a cake. Over time, oxygen radicals or other side reactions can block the catalyst surface, hindering hydrogen production. Similarly, poor design in flow fields can lead to starvation or flooding effects, reducing efficiency. Heuer’s system enables researchers and operators to detect such issues early, allowing adjustments in operating parameters to extend the cell's life and maintain optimal performance.
Improving efficiency by just 1% in a 1 MW electrolyzer can yield 160 additional tons of hydrogen, worth €800,000 over its operational life. The CureTemp system enhances cell behavior understanding, leading to more efficient designs, better material choices, and predictive maintenance to reduce downtime and costs. Integrating such advanced monitoring tools boosts performance and maximizes returns, meeting the rising demand for sustainable hydrogen production.
