Energie-Frage der Woche: Wie wird aus Wasserstoff elektrischer Strom?

Brennstoffzellen wandeln auf dem wohl elegantesten Weg energiehaltige Brennstoffe in elektrischen Strom um – ohne den Ausstoß von CO2 oder anderen Abgasen, wenn Wasserstoff als Brennstoff verwendet wird. Bereits 1838 gelang dem deutsch-schweizerischen Chemiker Christian Friedrich Schönbein mit zwei Platindrähten das erste Mal, aus Wasserstoff und Sauerstoff eine elektrische Spannung aufzubauen. Seitdem sind zahlreiche Brennstoffzellentypen bis zur Marktreife entwickelt worden. Welches gemeinsame Prinzip liegt ihnen zugrunde? read more

Energy question of the week: How can electricity be generated from hydrogen?

Fuel cells are surely the most elegant way of converting energy-rich fuels into electricity without emitting any carbon dioxide or other exhaust gases if hydrogen is the type of fuel used. Back in 1838, the German-Swiss chemist Christian Friedrich Schönbein successfully generated an electrical voltage from hydrogen and oxygen for the first time, using two platinum wires to accomplish this feat. Since then, many different types of fuel cells have been developed to a commercially marketable standard. What underlying principle do they all have in common? read more
