The PEM Interdigitated Fuel Cell is a high performance fuel cell stack with a new separator plate design giving a highly efficient reactant transport, and with a careful connector design providing corrosion resistance. The stack is built with robust quality and durability allowing for repeated assembly and dis-assembly.

The new separator plate includes an interdigitated flow field design, so that reactant is forced through the porous gas diffusion layer (GDL).  The forced flow helps to transport reactant to the reactive catalyst layer thus reducing mass transfer limitation and increase power output.  The fuel connection is specifically designed and made with a direct connection between the graphite separator plate and Nylon (or Teflon) fittings, so that fuel and the current collector and end plate do not come in contact, making them corrosive resistant.

The stack with the interdigitated plate is available in 50 cm².  A cooling plate is also available for the 50 cm² stack.
