Zusammenfassung:	A bipolar plate assembly (100) includes a first frame member (105), a second frame member (110), and a membrane electrode assembly (120). The first frame member (105) has a first side (125) and a second side (127). The first side (125) has a first side protuberance (130). The second frame member (110) includes a first side (135) and a second side (140). The second side (140) has a second side recess (145). The membrane electrode assembly (100) has an anode plate (150) and a cathode plate (155). A portion of the membrane electrode assembly (100) is disposed between the first frame member (105) and the second frame member (107). The portion of the membrane electrode assembly (100) has a juxtaposition of the anode plate (150) and the cathode plate (155). The first side protuberance (130) of the first frame member (105) deforms the portion of the membrane electrode assembly (100) into the second side recess (145) of the second frame member (110).
