Event Picture:

The performance and durability of proton exchange
membrane fuel cells (PEMFCs) are closely linked to effective
water management strategies. Inadequate water balance results in
polymer electrolyte membrane (PEM) dehydration or water
flooding leading to performance loss and possible cell failure.
Exploiting the contrast from liquid water absorption and
transparency of dielectric materials, such as polymers, at terahertz
frequencies, we apply a simple, compact terahertz imaging system
to image water build-up in a terahertz-transparent PEMFC,
supported by high-resolution optical gauging.
