Comprehensive review
Multi-length scale characterisation of compression on metal foam flow-field based fuel cells using X-ray computed tomography and neutron radiography
Compression process decreases pore size and narrows PSD of metal foams. Facilitates effective water removal due to high pressure drop.
Effect of reactant gas flow orientation on the current and temperature distribution in self-heating polymer electrolyte fuel cells (*)
Self-heating in unheated PEFCs increases cell temperature and recovers voltage. Temperature distributions form by uneven current, reactant and water distributions. A uniform temperature distribution could minimise performance degradation over time.
Microstructural evolution of battery electrodes during calendaring
Electrode with coarse architecture is prone to self-arrangement under calendaring. Calendaring exacerbates reaction heterogeneity and underutilisation of capacity.
Use of X-ray computed tomography for understanding localised, along-the-channel degradation of polymer electrolyte fuel cells
Combined miniature fuel cell and X-ray CT. Significant regional variation in the extent of cathode degradation. Fuel cell carbon corrosion ASTs do not age electrodes homogeneously.

Characterisation of water management in metal foam flow-field based polymer electrolyte fuel cells using in-operando neutron radiography
Metal foam flow field enhances the uniformity in water distribution and is more tolerant to dehydration. Susceptible to flooding at low current density.

Catalyst durability, performance, TEM and XPS analysis of short-circuiting when used as an operational strategy to maintain PEFC temperature, hydration and performance.
A novel polymer electrolyte fuel cell flow-field: The through-plane array
Novel flow field concept for PEFC. Micro-hole array allows gas to exit under lands. Lower backpressure than parallel or serpentine designs.
