Porous Transport Layers for PEM Fuel Cell and Thermoelectric Cells

RESEARCH THEME 7

Objective:
The objective is to apply knowledge from research themes 1-6 to:

  1. Design more energy- efficient electrochemical systems tailoring for instance their porous transport layer.
  2. Describe the role of buoyancy in CO2 sequestration in reservoirs.
  3. Predict hydraulic fracturing in three dimensions.
The fuel cell supply system for gas was improved by introducing a microporous layer into the nanoporous catalytic layer of a PEMFC, see Zlotorovicz et al. J. Power Sources, 287 (215) 472
We will now optimize access of gas through the microporous layer, see Kjelstrup et al. Energy and Fuels 24 (2010) 5097.
