Internationaal team maakt goedkoper waterstofcellen met roest

AMSTERDAM – Zwitserse en Israëlische wetenschappers hebben waterstofcellen uit zonne-energie weten te maken met roest.

Waterstofcellen, Dit meldt de technische universiteit van het Zwitserse Lausanne.

De onderzoekers hebben de meest efficiënte photoelectrochemical cel (PEC) gemaakt na uitvoerige configuratie op een nanostructuur van ijzeroxide, oftewel roest.

Door deze in het water te leggen en in contact te laten komen met zonlicht worden er waterstofcellen geproduceerd.


Testen met een prototype van 10 bij 10 centimeter waren succesvol en de onderzoekers denken dat ze voor een gemiddelde van 5 euro per kilo per PEC kunnen produceren. Op dit moment kost een kilo ongeveer 15 euro.

Onderzoek Michael Grätzel ziet de ontdekking als een heilige graal voor het onderzoek naar waterstof. De volgende stap is een industriële ontwikkeling van de PEC. De wetenschappers hopen daarvoor financiering los te peuteren van de Zwitserse overheid.

    Trump was surrounded at Friday’s event by officials from Customs and Border Protection as well as surviving family members of those who have loved ones killed by undocumented immigrants. Attorney General William Barr was also at the President’s veto event.
    While some lawmakers including some Republicans — have argued against the President’s use of national emergency powers in this instance, the Justice Department set forth a robust defense of the President’s authority to do so in a letter to Senate Majority Leader Mitch McConnell earlier this month, according to a copy obtained by CNN on Friday.
    “The President acted well within his discretion in declaring a national emergency concerning the southern border,” wrote Assistant Attorney General Stephen Boyd, setting out the legal basis for the proclamation under the National Emergencies Act and additional statutory authorities, which largely tracks an internal memo issued by the Office of Legal Counsel at the Justice Department.
