Bipolar half case structure of bipolar plate for fuel cell, has depositor that is folded over in middle of bar lying axis, such that edge of depositor up to lateral edges of bar, and lateral edges of bar up to middle are cut-out

摘要

The case structure (1) has discharge openings (4) for operation mediums, which are connected with the inner channels (6) over a channel (5). The projecting mold (7) is formed in the shoulder portion (10) at the opening (11) of the recess (3), and is connected to the lateral free region (8) of the case over the bar (9). An integrally connected depositor (12) is folded over in the middle of bar lying axis (13). The edge (14) of the depositor up to the lateral edges (15) of the bar, and the lateral edges of the bar up to the middle are cut-out along bar lying axis.
