BIPOLAR PLATE FOR A FUEL CELL WITH A POLYMER MEMBRANE

摘要

The invention relates to a distribution plate for a fuel cell, comprising a first plate (11) of an electrically conducting material having an inner face and an outer face (110) interacting with an ion-exchange membrane, the outer face (110) including a distribution channel network (11)for a first gas, the distribution plate including a second plate (12) of an electrically conducting material having an outer face and an inner face(12i) to be applied against the inner face of the first plate (11), a channel network (122) for circulating a coolant being provided on the inner face of the first plate (11) or on the inner face (12i) of the second plate (12),or on both, the plates being connected by a uniform layer of an electrically conducting binder material (2) that covers the inner face of each of the first and second plates.
