The cell voltage is monitored to determine the quality of the hydrogen from biogas utilising the high sensitivity of fuel cell \u00a0to harmful components in the feed gases. The result is a voltage decrease, thus reducing performance of the fuel cell stack. Both test cells are identical in structure and are used under the same operating conditions. Increased voltage differences between the two fuel cells in operation indicate a declining quality of the bio-hydrogen and the supply to the gas station can be stopped immediately. This ensures, that biohydrogen with decreasing quality only contaminates the inexpensive replaceable single stacks and doesn\u2019t destroy complete fuel cell systems.<\/p>\n<ul>\n<li>Department Fuel cells and systems<\/li>\n<li>fuel cell systems<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n\n\n<section class=\"latest-news latest-news--white\">\n            <h2 class=\"latest-news__heading\">More News<\/h2>\n                <div class=\"latest-news__grid\">\n                                            <div class=\"latest-news__item\">\n                    <a href=\"https:\/\/zbt.de\/en\/news\/tuv-sud-glasgow-hydrogen-test-field-refuelling\/\" class=\"news-card\" title=\"T\u00dcV S\u00dcD Glasgow visits the ZBT\u2019s hydrogen test field\">\n    <div class=\"news-card__header\">\n        <figure class=\"news-card__figure\">\n            <img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/zbt.de\/app\/uploads\/2026\/10\/TUeV-SUeD-NEL-ZBT-2026-orange-1024x576.jpg\" class=\"news-card__image wp-post-image\" alt=\"\" srcset=\"https:\/\/zbt.de\/app\/uploads\/2026\/10\/TUeV-SUeD-NEL-ZBT-2026-orange-1024x576.jpg 1024w, https:\/\/zbt.de\/app\/uploads\/2026\/10\/TUeV-SUeD-NEL-ZBT-2026-orange-300x169.jpg 300w, https:\/\/zbt.de\/app\/uploads\/2026\/10\/TUeV-SUeD-NEL-ZBT-2026-orange-768x432.jpg 768w, https:\/\/zbt.de\/app\/uploads\/2026\/10\/TUeV-SUeD-NEL-ZBT-2026-orange-1536x864.jpg 1536w, https:\/\/zbt.de\/app\/uploads\/2026\/10\/TUeV-SUeD-NEL-ZBT-2026-orange-2048x1152.jpg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/>\n        <\/figure>\n    <\/div>\n    <div class=\"news-card__body\">\n        <time class=\"topic-card__published\" datetime=\"2026-10-07T10:00:00+00:00\">\n            7.
