He introduced passivation gradients in the categories of Pt\/C loading, the ionomer-carbon ratio and the ionomer equivalent weight \u2013 both individually and in combination.<\/p>\n<p>Electrochemical impedance spectroscopy was used to reveal the <strong>underlying transport and kinetic effects<\/strong>. \u2018This strategy enabled us to clearly separate the contributions of kinetic, mass transport and ohmic resistance effects,\u2019 explains Caidi.<\/p>\n<h4>Graded catalysts significantly increase performance<\/h4>\n<p>And the effort paid off: the fully graded catalyst ultimately showed a <strong>32% increase in performance<\/strong> at 0.6 V (wet conditions) and a 17% increase at 0.6 V (dry conditions) compared to the pre-optimised reference. These results underscore the critical importance of combining robust base optimisation with a <strong>rational gradient design<\/strong>, which offers a comprehensive path to performance enhancement while <strong>minimising precious metal consumption<\/strong>.<\/p>\n<\/div>\n<\/section>\n\n\n<section class=\"image\">\n        <img loading=\"lazy\" decoding=\"async\" width=\"1427\" height=\"744\" src=\"https:\/\/zbt.de\/app\/uploads\/2025\/09\/grafiken-gradienten-design-in-katalysatoren-fuer-pem-brennstoffzellen.jpg\" class=\"attachment-full size-full\" alt=\"Graphs from a study on gradient design in catalyst layers for PEM fuel cells\" srcset=\"https:\/\/zbt.de\/app\/uploads\/2025\/09\/grafiken-gradienten-design-in-katalysatoren-fuer-pem-brennstoffzellen.jpg 1427w, https:\/\/zbt.de\/app\/uploads\/2025\/09\/grafiken-gradienten-design-in-katalysatoren-fuer-pem-brennstoffzellen-300x156.jpg 300w, https:\/\/zbt.de\/app\/uploads\/2025\/09\/grafiken-gradienten-design-in-katalysatoren-fuer-pem-brennstoffzellen-1024x534.jpg 1024w, https:\/\/zbt.de\/app\/uploads\/2025\/09\/grafiken-gradienten-design-in-katalysatoren-fuer-pem-brennstoffzellen-768x400.jpg 768w, https:\/\/zbt.de\/app\/uploads\/2025\/09\/grafiken-gradienten-design-in-katalysatoren-fuer-pem-brennstoffzellen-1320x688.jpg 1320w\" sizes=\"auto, (max-width: 1427px) 100vw, 1427px\" \/>\n    \n<\/section>\n\n<section class=\"text-teaser text-teaser--white\">\n  <h2 class=\"text-teaser__heading\"><\/h2>\n  <div class=\"text-teaser__text\"><p>These improvements directly address two of the most pressing challenges in fuel cell research: <strong>efficient catalyst utilisation<\/strong> and robust performance under water-limited operating conditions.<\/p>\n<p>The publication is highly relevant to the field of research as it bridges the gap between fundamental electrochemical understanding and practical electrode design strategies.
