ECC-Air-Ni
Test cell dedicated to the characterization of gas diffusion electrodes in alkaline aqueous electrolytes
The ECC-Air-Ni is another member of the modular ECC series. In contrast to the standard ECC-Air test cell, the current collectors are made of nickel instead of stainless steel. This way, the ECC-Air-Ni is stable against corrosion in alkaline aqueous electrolytes.
Basically, the cell accommodates a counter electrode on the cell bottom, a gas diffusion electrode on top and a separator in between. The upper gas diffusion electrode is contacted by and “breathes” through the nickel perforated plate (current collector) above. The cell lid is equipped with one port for gas inlet and one for gas outlet, so that the incoming gas passes along the backside of the gas diffusion electrode and leaves the cell through the siphon. The ECC-Air-Ni can be used with a reference electrode, which is located at the separator edge.
