PAT-Cell for in-situ gas analysis in a flow-through set-up

Our versatile test cell for in-situ gas analysis

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 syringe.

The cell stack is placed on top of a perforated or grooved current collector (flow field), which is to be purged with a gentle stream of gas. The lower electrode must be gas permeable, so as to allow for gas exchange with the feed gas. Typically, the cell is used with gas diffusion electrodes (such as for Li-air) or with Li-ion battery electrodes with a meshed current collector. The special design minimizes backmixing of the gas from the flowfield back into the headspace, and is thus very suitable for time-resolved gas analysis with a mass spectrometer, for example.
