Principles of Design and Mass Transport

pH Measurement in the electrolyte cycle of a VRB

Within the scope of research and development carried out at HAW Hamburg, the interaction between the relevant process and material parameters for the operation of a VLRFB shall be examined. The influence of these parameters on the process control shall be explored and interdependencies shall be identified. Objective of this investigation is the detection of design principles for micro tubular VLRFB cells and the corresponding manufacturing and operation methods.

Computer based models for the examination of certain phenomena will assist the experimental research work in order to achieve a cost and time effective development of a micro tubular cell prototype.

One focus of the work is the examination and optimization of the mass transport in the porous structure of the bifunctional air/water steam electrode (see figure).
