Optimal <strong>dimensioning of the pollutant filter<\/strong> can prevent irreversible performance losses. <\/p>\n<h4>Optimised cathode air filters<\/h4>\n<p>In order to better understand how pollutant filters can be designed efficiently, ZBT and its partners in the KaLiBer project are recording <strong>harmful gas concentration<\/strong> on agricultural land, construction sites and in port areas and investigating the combination of air filters and fuel cells in situ. The aim is to use these measurements to develop future cathode air filters with the following features: <\/p>\n<ul>\n<li>Reduction of air filter replacement intervals<\/li>\n<li>Customised filter concepts for different applications<\/li>\n<li>Extension of the service life of fuel cell stacks<\/li>\n<\/ul>\n<h4>Our contribution<\/h4>\n<p>Within the joint project, ZBT is focusing on developing a test methodology for <strong>air filters on a laboratory<\/strong> scale and establishing the necessary qualification capacities. To this end, a <strong>test bench<\/strong> is being developed and set up, and high-precision <strong>analytics<\/strong> are being integrated to detect harmful gas concentrations before and after the filter element. Integrating the filter into the fuel cell cathode string makes it possible to test the filter performance under realistic conditions. This test setup allows us to gain insights such as:   <\/p>\n<ul>\n<li>In-situ influence of harmful gases and filter types on the fuel cell<\/li>\n<li>Effects of air pollution on MEAs in non-road applications<\/li>\n<li>Harmful gas exposure at locations with high air pollution<\/li>\n<\/ul>\n<h4>Expected results and benefits<\/h4>\n<p>The experience and results from the project should enable a well-founded <strong>assessment of filter quality<\/strong> and a more precise definition of replacement intervals. This will make a significant contribution to the optimisation of fuel cell systems for applications in demanding environmental conditions. <\/p>\n<p>The KaLiBer research project is funded by the German Federal Ministry for Economic Affairs and Energy as part of the 8th Energy Research Programme.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Project title:<\/strong><br \/>\nBMWK joint project KaLiBer \u2013 Development and verification of cathode air filters for stationary fuel cell systems in the maritime, construction and agricultural sectors; sub-project: Filter testing methodology and investigation of the influence of harmful gases on the cathode<\/p>\n<p><strong>Project coordinator<\/strong><br \/>\nHydac FluidCareCenter<\/p>\n<p><strong>Project partners<\/strong><\/p>\n<ul>\n<li>Research Centre J\u00fclich<\/li>\n<li>ZBT &#8211; The Hydrogen and Fuel Cell Center<\/li>\n<li>Zeppelin Power Systems<\/li>\n<\/ul>\n<p><strong>Project sponsor<\/strong><br \/>\nProjekttr\u00e4ger J\u00fclich<\/p>\n<p><strong>Associated partners<\/strong><\/p>\n<ul>\n<li>PowerCell Deutschland<\/li>\n<li>Orten Fahrzeugbau<\/li>\n<li>AGCO<\/li>\n<\/ul>\n<p><strong>Project duration<\/strong><br \/>\n01.08.2024 &#8211; 31.07.2027<\/p>\n<p><strong>Funding code<\/strong><br \/>\n03EN5043C<\/p>\n<p><a href=\"https:\/\/zbt.de\/en\/institute\/departments\/fuel-cell-systems\/\">Fuel Cell Systems Department<\/a><\/p>\n<\/div>\n<\/section>\n<section class=\"image-collection image-collection--white\">\n                <div class=\"image-collection__grid\">\n                            \n                                <div class=\"image-collection__item\">\n                  <a href=\"https:\/\/zbt.de\/app\/uploads\/2024\/10\/Logo_Bundesministerium_Wirtschaft_Klimaschutz.gif\"  data-fancybox=\"image-collection__6aa4fbbfe6dad\"   class=\"image-collection__link\">\n                      <img decoding=\"async\" src=\"https:\/\/zbt.de\/app\/uploads\/2024\/10\/Logo_Bundesministerium_Wirtschaft_Klimaschutz.gif\" alt=\"\">\n                  <\/a>\n                                  <\/div>\n                                    <\/div>\n    <\/section>\n\n<script>\n    document.addEventListener('DOMContentLoaded', function () {\n        \/\/ Pass PHP-generated block_id into JS\n        const blockId = \"6aa4fbbfe6dad\";\n\n        \/\/ Initialize Fancybox for this block\n        Fancybox.bind(`[data-fancybox=\"image-collection__${blockId}\"]`);\n    });\n<\/script><section class=\"latest-project latest-project--light\">\n            <h2 class=\"latest-project__heading\">Further projects<\/h2>\n    \n            <div class=\"latest-project__grid\">\n                                                                                                <div class=\"latest-project__item\">\n                            <a href=\"https:\/\/zbt.de\/en\/projects\/past-el\/\" class=\"project-card\" title=\"pAST-EL - Predictive AST Protocols for Alkaline Electrolysis\">\n    <div class=\"project-card__header\">\n        <figure class=\"project-card__figure\">\n            <img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"644\" src=\"https:\/\/zbt.de\/app\/uploads\/2026\/08\/DSC_7095-1024x644.jpg\" class=\"project-card__image wp-post-image\" alt=\"\" srcset=\"https:\/\/zbt.de\/app\/uploads\/2026\/08\/DSC_7095-1024x644.jpg 1024w, https:\/\/zbt.de\/app\/uploads\/2026\/08\/DSC_7095-300x189.jpg 300w, https:\/\/zbt.de\/app\/uploads\/2026\/08\/DSC_7095-768x483.jpg 768w, https:\/\/zbt.de\/app\/uploads\/2026\/08\/DSC_7095-1536x966.jpg 1536w, https:\/\/zbt.de\/app\/uploads\/2026\/08\/DSC_7095-2048x1287.jpg 2048w, https:\/\/zbt.de\/app\/uploads\/2026\/08\/DSC_7095-1320x830.jpg 1320w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/>\n        <\/figure>\n    <\/div>\n    <div class=\"project-card__body\">\n        <time class=\"project-card__published\" datetime=\"2026-08-17T15:41:27+00:00\">\n            17.
