    摘要: A thermal management system of an electrochemical engine comprises a radiator provided with a wicking mechanism, a coolant pump fluidly connected to the radiator, a water tank, and a water pump. The water tank is located in the void spaces around fuel storage tanks, and may be filled directly or with reclaimed water from a vapor by-product of the electrochemical engine. The water pump is operable to supply water from the water tank to the wicking mechanism during peak power and/or hot day conditions. Moisture in the vapor by-product may be condensed with the excess cooling capacity of the radiator under less severe cooling conditions. Under freezing conditions, exhaust or coolant from the electrochemical engine may be used to unfreeze water in the tank and wicking mechanism supply lines.

    摘要: The present invention isolates the fluid streams flowing into and out of a fuel cell stack from the terminal plates so that the fluid streams and terminal plates do not come into contact with one another. The prevention of the fluid streams from contacting the terminal plate eliminates corrosion concerns associated with the terminal plate. The present invention accomplishes this isolation through the use of headers having fluid passageways therein that route the fluid streams in and/or out of the fuel cell stack while preventing contact between the fluid streams and the terminal plate.

    摘要: The present invention is directed to an electroconductive element within an electrochemical cell that improves water management. The electroconductive element comprises an impermeable electrically conductive element and a porous liquid distribution media disposed along a major surface of the conductive element. Preferably, the liquid distribution media is in direct contact and fluid communication with a fluid distribution layer disposed between the membrane electrode assembly (MEA) and the liquid distribution media, so that liquids are drawn from the MEA through the fluid distribution layer to and through the liquid distribution media. The liquid distribution media transports liquids away from the MEA in the fuel cell. Methods of fabricating and operating fuel cells and electroconductive elements according to the present invention are also contemplated.
