A valve system includes a valve, a valve controller, and a heat exchanger. The valve is configured to open and close a control device in response to a working fluid. The controller controls the flow of the working fluid to and from the valve. The heat exchanger is mounted between the valve and the valve controller. The heat exchanger receives the working fluid from the valve, cools the working fluid using a cooling stream, and delivers cooled working fluid to the valve controller.

Cathode exhaust of an evaporatively cooled fuel cell stack () is condensed in a heat exchanger () having extended fins () or tubes () to prevent pooling of condensate, and/or having the entire exit surface of the condenser rendered hydrophilic with wicking () to conduct water away. The cathode exhaust flow paths may be vertical or horizontal, they may be partly or totally rendered hydrophilic, and if so, in liquid communication with hydrophilic end surfaces of the condenser, and the condensers () may be tilted away from a normal orientation with respect to earth's gravity.

A fuel cell includes an inlet manifold that communicates with an inlet pipe. The inlet pipe enters the inlet manifold at a port. A baffle is positioned about the port. The baffle captures and directs fuel away from a side of the inlet manifold that will face a cell stack. A fuel cell incorporating such an inlet manifold is also claimed.

A self-blunting needle assembly comprises a hollow needle, which may be of conventional construction having a needle mouth and a needle shank terminating in a puncture tip, has mounted within it a blunting member including an elongate probe which slidably fits within the bore of the needle shank. The probe terminates in a distal tip which is initially positioned short of the puncture tip of the needle so as not to interfer with injection of the needle either into a patient or into a connecting device. After injection, the blunting member is advanced to an extended position in which its distal tip protrudes beyond the puncture tip, thereby effectively blunting the needle. This protruding probe disables the needle from a re-use and blunts it sufficiently to prevent or greatly reduce accidental needlestick wounds. A mechanical extension member, such as a pin or fluid flowing through the needle may be used to advance the blunting member to its extended position.
