NPL novel reference electrode shows that cathode, not anode, is source of potential decay in PEM water electrolyzers

Green Car Congress

Scientists from the National Physical Laboratory (NPL) in the UK have developed a novel reference electrode for polymer electrolyte membrane water electrolyzers (PEMWEs) and used it to measure the electrochemical surface area (ECSA) of Pt catalysts in situ for the first time. Reference electrode configuration. Source: NPL.

Audi offers 22 kW AC charging option on e-tron

Green Car Congress

The standard mode 3 cable, with which all e-tron models can charge at public terminals, has already been converted to a charging capacity of 22 kW. The new charging system connect, which Audi offers for home garages, is also designed for a charging capacity of up to 22 kW. Charging planning then considers forecast periods of sunshine.

Fraunhofer team developing continuous rapid production line for fuel cell components

Green Car Congress

The many millions of vehicles will need many millions of fuel cells to convert hydrogen into power, but as yet, Europe has no mass production facility that could cover this demand. Specifically, this is about producing the fuel cell stack on which hydrogen is converted to water and the energy is collected.
