FUEL CELL ASSEMBLY TECHNIQUE Russian patent published in 2008 - IPC H01M8/02 

FIELD: fuel cells and medium flow distribution plates for fuel cells using solid polymeric electrolyte.

SUBSTANCE: proposed fuel cell has fluid flow field plates functioning as channels fluid to electrode surfaces. Formed on fluid flow field surface are many channels running on plate surface in the form of definite structure to define active area of plate. Plurality of channels running from first edge of distribution foil to second one are formed on distribution foil surface. Channels end in second edge at locations actually coinciding with respective locations of field distribution plate channels at water injection points. Covering foil is disposed on top of distribution foil so that it covers distribution foil channels thereby forming water channels between two layers of foil.

EFFECT: improved method and device for controlled water supply to separate channels on fluid flow plates; facilitated manufacture and assembly.
