Page 4: Product Description
PAT-Cell-Gas 1 Product description The PAT-Cell-Gas is a test cell dedicated for in-situ gas analysis of battery materials in a flow- through set-up. For that purpose, the test cell features a gas inlet and outlet and optionally a built-in pressure sensor and a valve port for gas sample removal with a syrin ge. The test cell is typically connected to peripherical equipment for gas supply and gas analysis. - Page 5 User Manual PAT-Cell-Gas Schematic view: Gas inlet and outlet Inlet Outlet Page 5 of 23 Release 1.34...

Page 9: Assembly Of The Pat-Cell-Gas
PAT-Cell-Gas 5 Assembly of the PAT-Cell-Gas This section describes how to assemble the PAT-Cell-Gas test cell. A more detailed description of the PAT-Core can be found in a separate manual. Note: The assembly has to take place under the protective atmosphere in a glove box. - Page 10 User Manual PAT-Cell-Gas Put the special lower plunger onto the worktop with the perforated plate / flow field pointing upwards. Make sure that the O-ring seal at the bottom of the plunger is in place. Make sure that the perforated plate is properly inserted on top of the plunger (only w hen using the two-piece perforated version of lower plunger) Put the insulation sleeve onto the worktop with the smaller side pointing upwards .

Page 11: Working Modes Of The Pat-Cell-Gas
User Manual PAT-Cell-Gas 6 Working modes of the PAT-Cell-Gas There are two dedicated lower plunger available for the PAT-Cell-Gas for different testing purposes. 6.1 Mode 1: Air mode The lower plunger with perforated plate allows for electrochemical characterization of gas diffusion electrodes used for instance in Li-air batteries. - Page 12 User Manual PAT-Cell-Gas 6.2 Mode 2: OEMS mode The PAT-Core setup using a lower plunger with flow field provides almost perfect plug-flow of the purge gas being essential for quantitative time-resolved analysis. Gases evolved or consumed at the working electrode may be analysed through the composition change of the gas stream that is to be passed along the spiral-type flow field below the working electrode.
