Nature-inspired fuel cells

In this project, the Centre for Nature Inspired Engineering will design, construct and test a lung-inspired fuel cell with globally optimized, hierarchical structure from nanomaterial to device level.

The lung-inspired architecture combines attractive features that will be translated to fuel cell design:

  • an ability to bridge length scales, and easily scale-up – irrespective of size – while preserving microscopic function (cells in the lung, active sites in catalysis)
  • realizing uniform distribution and collection of various species (molecular, ionic) and heat
  • minimizing transport resistance and thermodynamic losses, thanks to optimized dimensioning of the hierarchical channel size distribution, for specific technical requirements
  • increased adaptability and durability

Researchers: Jason Cho, Toby Neville and Panos Trogadas.
