However, when it comes to alternative drives for aviation, <strong>minimum weight<\/strong> is important. The ZBT and its project partners are therefore jointly developing a <strong>fuel cell system with air cooling<\/strong> for unmanned aerial vehicles (UAVs, drones) and aircraft with a take-off weight of between 25 kilograms and two tons.  <\/p>\n<p>The aim of the BeHyPSy project is to develop, integrate and test an innovative propulsion system in a relevant power range that is based on <strong>hydrogen as an energy source<\/strong>. The drive system will be integrated into a laboratory prototype, characterized in the overall system and validated in an aircraft. The aim is to demonstrate that the scaled system architecture can also be used at higher take-off weights, which will open up an important market.  <\/p>\n<p>In contrast to conventional fuel cell systems in the high power range (&gt;50kW), the system developed here does not use liquid cooling, which significantly reduces weight and volume. This means that the <strong>air management of the fuel cell system<\/strong> is of central importance, as both the reactant supply and the cooling air supply must be adapted to the system. <\/p>\n<p>Another important feature of the desired system architecture is the <strong>multi-phase electric motor<\/strong> to increase reliability and availability. Each phase of the electric motor is supplied with power by a multi-stack fuel cell system. <\/p>\n<p>The aim of the ZBT&#8217;s work within the project is &#8220;<strong>Lightweight fuel cell development<\/strong> for aviation applications&#8221; in order to meet this system concept with the development of particularly lightweight, air-cooled fuel cell stacks.<\/p>\n<p><strong>The most important approaches to increasing power density are<\/strong><\/p>\n<ul>\n<li>the use of thin, formed metal foils for the bipolar plates compared to the composite bipolar plates primarily used in air-cooled fuel cell stacks,<\/li>\n<li>increasing space utilization at cell level through particularly compact cell designs and seal integration,<\/li>\n<li>the development of a lightweight bracing system<\/li>\n<li>an increased level of integration<\/li>\n<\/ul>\n<p>If these measures succeed in reducing the stack weight, the potential of the system architecture can be fully exploited.<\/p>\n<p>&nbsp;<\/p>\n<h5><strong>Partner<\/strong><\/h5>\n<ul>\n<li>ZAL &#8211; Zentrum f\u00fcr angewandte Luftfahrtforschung<\/li>\n<li>BREEZER Aircraft<\/li>\n<li>HAW &#8211; Hochschule f\u00fcr angewandte Wissenschaften Hamburg<\/li>\n<li>HSU &#8211; Helmut-Schmidt-Universit\u00e4t Hamburg<\/li>\n<li>RST &#8211; Rostock System-Technik<\/li>\n<li>ZBT &#8211; Zentrum f\u00fcr BrennstoffzellenTechnik<\/li>\n<\/ul>\n<h5><strong>LUFO-Nr<\/strong><\/h5>\n<p>20M2249<\/p>\n<h5><strong>Funding provider:<\/strong><\/h5>\n<p> Bundesministerium f\u00fcr Wirtschaft und Klimaschutz<\/p>\n<h5><strong>Authorization period<\/strong><\/h5>\n<p>01.05.2024 &#8211; 31.07.2027<\/p>\n<p><a href=\"https:\/\/zbt.de\/en\/institute\/departments\/fuel-cells-stacks\/\">Department Fuel Cells and Stacks<\/a><\/p>\n<\/div>\n<\/section>\n\n\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__6a8d7d3cf3410\"   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 = \"6a8d7d3cf3410\";\n\n        \/\/ Initialize Fancybox for this block\n        Fancybox.bind(`[data-fancybox=\"image-collection__${blockId}\"]`);\n    });\n<\/script>\n\n<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.
