摘要： A sealing technique is provided for forming complex and multiple seal configurations for fuel cells and other electrochemical cells. To provide a seal, for sealing chambers for oxidant, fuel and/or coolant, a groove network is provided extending through the various elements of the fuel cell assembly. A source of seal material is then connected to an external filling port and injected into the groove network, and the seal material is then cured to form the seal. There is thus formed a "seal in place", that id robust and can be bonded, where possible, to individual elements of the fuel cell assembly. This avoids the difficulty, labor intensive cost and complexity of manually assembling many individual gaskets into complex groove shapes and the like. The seal material can be selected to be comparable with a wide variety of gases, liquid coolants and the like.

摘要： In a fuel cell, at least one humidification cell stack (30, 40) is provided as an extension of the fuel cell. The cells of the humidification cell stack can be structurally similar to and include the same membrane as the individual cells of the fuel cell stack (20). Flows of fuel (33, 45) and oxygen (35, 43) are then arranged to pass through the humidification cell stack for exchange of moisture. Preferably, there are humidification sections at either end of the fuel cell stack, to enable moisture exchange between incoming fuel (54) and discharged oxygen (38) to one end and incoming oxygen (66) and discharged fuel (60) at the other end. The arrangement is expected to enhance uniform operating conditions within the fuel cell stack itself, so as to ensure optimum operating conditions throughout the fuel cell stack.
