The course of characterisation methods for describing the behaviour of fuel cells and water electrolysers covers the main aspects of construction and operation. The methods range from characterising constituent materials used to make components and single cells, to short stacks and finally through to full stacks and systems. The need to address lifetime degradation and operational changes is achieved by treating characterisation before, during and after operation, in other words both spatial and temporal considerations are explained.
Aim of the course
Last update: Paidar Martin doc. Ing. Ph.D. (07.11.2022)

The outcomes of the module will provide understanding and competence in the following areas-

• Inspect and appraise the performance of fuel cells in terms of stability, power output, longevity;

• Plan and design experimental procedures to critically evaluate the operation of fuel cells, catalyst utilisation, electrochemically active catalyst surface area and poisoning;

• Assess and evaluate the different electrochemical concepts including cyclic voltammetry, electrochemical impedance spectroscopy, chronoamperometry to study fuel cells components;

• Compare, differentiate and analyse different material characterisation techniques;

• Evaluate different material properties and requirements (morphology, conductivity, water retention etc) for electrocatalysts, catalyst supports, conducting membranes and other fuel cell components by combining electrochemical and material characterisation.
