ECC-Opto-Gas
Test cell for optical characterization of gas diffusion electrodes in metal-air batteries.
The ECC-Opto-Gas is an in-situ test cell for the optical characterization of gas diffusion electrodes (GDE) in metal-air batteries. The cell features a sapphire window with a meander-shaped flow field, that can be purged with gas during charge/discharge. The ECC-Opto-Gas can be mounted on the stage of almost any light or Raman microscope in order to “look” through the transparent window onto the backside of the GDE. The cell is equipped for use with aprotic organic electrolytes.

Features
In-situ test cell for the optical characterization of gas diffusion electrodes (GDE) in aprotic organic electrolytes.
Minimized dimensions suitable for light and Raman microscopes working in the refl ective mode The cell stack, with the GDE on top, is placed below a sapphire window with a meander-shaped flow field. This way, the microscope is “looking” through the window onto the backside of the GDE. During charge/ discharge, a gentle stream of gas may be purged along the flow field. This way the electrochemical conversion taking place at the backside of the gas diffusion electrode can be observed. Materials in electrolyte contact are stainless steel 1.4404, PPS and PE. The disc-shaped GDE can have a diameter of up to 11 mm. The inspection area diameter is 10 mm. Cell assembly and electrolyte filling may be carried out inside a glove box. Once sealed, the cell may be operated outside the box at ambient atmosphere. Small and defined electrolyte volume down to 0.04 cm3. Connection to potentiostat/battery tester via 2 mm banana sockets Temperature operation range -20 to +70°CSpecifications
