Fluid flow plate for decreased density of fuel cell assembly

A fluid flow plate for a fuel cell assembly, said fluid flow plate comprising:

• a member having an inward face with an indentation thereon for forming a pocket between first and second outward faces of said fluid flow plate;
• and
• said member including said first outward face with a protuberance thereon for forming a portion of a flow channel for carrying fluid for said fuel cell assembly, said first outward face and said flow channel comprising first and second sections, said first section being connected with said second section;
• wherein said indentation forms said protuberance and said pocket decreases density of said fluid flow plate.

A fluid flow plate for a fuel cell assembly, said fluid flow plate comprising:

• first and second outward faces that each have respective flow channels thereon for carrying respective fluids, at least one of said fluids serving as reactant fluid for a fuel cell of said fuel cell assembly;
• said first outward face and flow channel thereof comprising first and second sectons, said firs section being connected with said second section;
• and
• a pocket formed between said first and second outward faces for decreasing density of said fluid flow plate.

A method of forming a fluid flow plate for a fuel cell assembly, said method comprising:

• forming an indentation on an inward face of a member in order to form a pocket between first and second outward faces of said fluid flow plate, wherein said pocket decreases density of said fluid flow plate;
• forming a protuberance on said first outward face in order to form a portion of a flow channel for carrying fluid for said fuel cell assembly;
• and
• employing first and second sections to form said first outward face and said flow channel, said first section being connected with said second section;
• wherein said forming of said indentation contributes to said forming of said protuberance.
