Cell Geometries

Different fuel cell shapes offer different advantages.  These are summarised below.


Planar Fuel Cell Geometry Features

  • Simple design, with electrolyte (or more recently anode) support.
  • Gases can be ducted either perpendicular (as shown) or parallel.
  • Main drawback is requirement of high temperature seals to prevent gas mixing.


Tubular Fuel Cell Geometry Features

  • Unit structure reduces thermal induced stresses in the stack.
  • Cathode support.
  • No requirement for seals.
  • Main drawback is it requires many expensive processing techniques.
