Micro-architectural alterations remove hurdles that hinder hydrogen fuel cells

This article was originally posted on Chemical Engineering Online.

Summary
UNSW researchers developed a redesigned internal microstructure for hydrogen fuel cells that enhances water removal and gas transport—addressing liquid water buildup, a key efficiency bottleneck. The new architecture also improves catalyst utilization, pointing to more efficient and reliable fuel-cell operation.

What remaining challenges (e.g., cost, durability, or hydrogen storage) do you think are most critical to solve alongside these micro-architectural advances?

Hydrogen fuel cells, which use hydrogen and oxygen to generate clean electricity and pure water, are considered among the most promising clean energy sources. However, the accumulation of liquid water inside hydrogen fuel cells is a major roadblock to efficient operation. Researchers from University of New South Wales have demonstrated a new internal fuel-cell microstructure that improves water removal and gas transport and increases catalyst utilization.

What’s the trade-off on pressure drop and compressor/blower parasitics? If it really clears water faster, can you show reduced purge frequency or wider humidifier setpoint margins during rapid load swings? Also need durability data: contact-angle drift under compression, freeze-thaw, and tolerance to sulfur/siloxane contamination.

We’ve found in liquid-handling gear that mixed wettability and capillary-break features beat pure hydrophobic treatments for preventing pooling. Are these micro-architectures using graded porosity/wettability (e.g., MPL/GDL PTFE gradients or anisotropic channels), and how do they hold up on stack compression set, freeze/thaw, and pressure-drop tradeoffs at automotive duty cycles?
