摘要： A method of monitoring and replacing fuel cells within a fuel cell stack assembly. The method includes measuring one or more operating conditions of a fuel cell within the fuel cell stack assembly. The method includes determining, using a processor, a state of health of the fuel cell based at least in part on the one or more operating conditions. The method includes detaching the fuel cell from an adjacent cell within the fuel cell stack assembly by removing a first electrically-conducing mating matrix associated with a first endplate of the fuel cell from a second electrically-conducing mating matrix associated with a second endplate of the adjacent cell. The method includes attaching a replacement fuel cell by mating a third electrically-conducing mating matrix associated with a third endplate of the replacement fuel cell with a fourth electrically-conducing mating matrix associated with a fourth endplate of the adjacent cell.

摘要： A method of producing an MEA includes a first joining step of joining an anode to one surface of a solid polymer electrolyte membrane to thereby form a joint body and a second joining step of joining a cathode to another surface of the solid polymer electrolyte membrane. In the first joining step, the solid polymer electrolyte membrane is attracted by suction and heated through the anode placed on a suction/heating surface of a suction/heating plate. In the second joining step, a stack body of the joint body and the cathode is pressed and heated in a stacking direction, between the suction/heating surface and a heating plate.

摘要： The invention relates to a bipolar plate (10) for a fuel cell stack. The bipolar plate (10) respectively has two profiled separator plates (12, 14) respectively having an active area (16) and two distribution areas (18, 20) for supplying and discharging reaction gases and coolant to or from the active area (16), wherein the separator plates (12, 14) are designed and arranged on top of each other such that the respective bipolar plate (10) has separate channels (28, 30, 32) for the reaction gases and the coolant, which channels connect ports (22, 24, 26) for reaction gases and coolant of both distribution areas (18, 20) to each other. In the mounted fuel cell stack, the channels (28, 30) for the reaction gases are respectively bordered by a surface of a separator plate (12, 14) and a surface of a gas diffusion layer (58).
It is provided that the bipolar plate (10) have an impermeable first dividing plate (38), which respectively divides the channels (28) for a reaction gas in an inlet area (40) of the active area (16) into two volume areas and extends in the flow direction (42) of the reaction gas, wherein only one volume area of the channel (28) is adjacent to the gas diffusion layer (58).
The subject matter of the invention is also a fuel cell stack with such bipolar plates (10), as well as a fuel cell system with a fuel cell stack according to the invention.
