Claim 17:
18. The bipolar plate assembly of claim 1, wherein:
the portion of the anode plate and the portion of the cathode plate disposed between the first frame member and the second frame member are at a coolant header of the bipolar plate assembly;
a portion of the proton exchange membrane is disposed between the first frame member and the second frame member at the coolant header of the bipolar plate assembly;
the first side protuberance of the first frame member contacts and deforms the portion of the cathode plate, which contacts and deforms the portion of the proton exchange membrane, which contacts and deforms the portion of the anode plate into the second side recess of the second frame member, thereby forming the seal therebetween;
the first frame member including a first coolant channel fluidly coupling the coolant header and a first coolant flow field, the first coolant flow field in thermal communication with the cathode plate; and
the second frame member including a second coolant channel fluidly coupling the coolant header and a second coolant flow field, the second coolant flow field in thermal communication with the anode plate.
