Research project

Title: Development of advanced diagnostic techniques to study degradation in PEM fuel cells

Supervisor: Dr Dan Brett

Polymer electrolyte fuel cell (PEFC) performance degradation originates from various mechanisms, and may involve all of the main components of the stack (i.e., electrolyte, electrodes and bipolar plates). These degradation mechanisms may be partially reversible (e.g., poisoning by fuel impurities) or irreversible (e.g., agglomeration of particles within electrodes) and may be exacerbated or remedied by excursions from steady-state operation, such as the cycling of temperature, electrical load, humidification level etc.

In order to develop more robust materials and to formulate operating regimes that minimise degradation, a clear understanding of the different degradation mechanisms needs to be achieved. As part of the Supergen Fuel Cell programme, this project is using advanced electrochemical diagnostic techniques to study PEFCs to establish and understand the various mechanisms of degradation.
