Editing Fuel cell (section)

====Trains====
Train operators may use hydrogen fuel cells in trains in an effort to save the costs of installing overhead electrification and to maintain the range offered by diesel trains. They have encountered expenses, however, due to fuel cells in trains lasting only three years, maintenance of the hydrogen tank and the additional need for batteries as a power buffer.<ref>{{Cite web |last=Hajek |first=Stefan |date=2023-08-17 |title=Wasserstoff- und Batterie-Züge: "Die Batterie setzt sich fast immer gegen den Wasserstoff durch |url=https://www.wiwo.de/unternehmen/dienstleister/wasserstoff-und-batterie-zuege-die-batterie-setzt-sich-fast-immer-gegen-den-wasserstoff-durch/29325672.html |access-date=2024-07-15 |website=www.wiwo.de |language=de}}</ref><ref>{{Cite web |last=Parkes |first=Rachel |date=2023-08-22 |title=Hydrogen will 'almost always' lose out to battery-electric in German rail transport: train manufacturer |url=https://www.hydrogeninsight.com/transport/hydrogen-will-almost-always-lose-out-to-battery-electric-in-german-rail-transport-train-manufacturer/2-1-1504868 |access-date=2024-07-15 |website=hydrogeninsight.com}}</ref> In 2018, the first fuel cell-powered trains, the [[Alstom Coradia Lint#iLint|Alstom Coradia iLint]] multiple units, began running on the Buxtehude–Bremervörde–Bremerhaven–Cuxhaven line in Germany.<ref>{{cite web |title=Fuel cell powered trains |url=https://www.alstom.com/solutions/rolling-stock/coradia-ilinttm-worlds-1st-hydrogen-powered-train |website=Alstom Coradia iLint}}</ref> Hydrogen trains have also been introduced in Sweden<ref>{{cite web |url=https://www.alstom.com/press-releases-news/2021/8/alstoms-coradia-ilint-hydrogen-train-runs-first-time-sweden |title=Alstom's Coradia iLint hydrogen train runs for the first time in Sweden|website=Alstom.com}}</ref> and the UK.<ref>{{cite web |title=Hydrogen trains in U.K. |url=https://rail.ricardo.com/campaigns/routes-to-railway-decarbonisation/hydrogen-traction/hydrogen-fuel-cell-rollingstock |website=HydroFlex}}</ref>
