Abstract: A droplet jetting device comprising a membrane layer defining a pressure chamber that is in fluid communication with a nozzle, the membrane layer carrying, on a membrane that covers the pressure chamber, an actuator for generating pressure waves in a liquid in the pressure chamber, the device further comprising a distribution layer bonded to the membrane layer on the side of the membrane and defining a supply line for supplying the liquid to the pressure chamber, the supply line being connected to the pressure chamber via a restrictor passage extending through the distribution layer in the thickness direction of that layer, and via a window formed in the membrane, characterized in that the restrictor passage has a uniform cross-section, and the membrane window is delimited by a contour that is inwardly offset from the contour of the restrictor passage on the entire periphery of the restrictor passage.

Abstract: System and methods for controlling and optimizing coolant system parameters in a fuel cell system to obtain a requested cabin temperature in a fuel cell vehicle are presented. A method for managing a temperature in a vehicle cabin may include receiving an indication relating to a desired vehicle cabin temperature and a plurality of measured operating parameters. Based on the measured operating parameters, a projected output temperature of a cabin heat exchanger may be estimated. A determination may be made that the projected output temperature of the cabin heat exchanger is less than the indication. Based on the determination a fuel cell coolant parameter may be adjusted.

Abstract: A system for conditioning the air in a passenger compartment of a fuel cell-powered vehicle is provided, the system including a metal hydride buffer and a hydrogen source, wherein the metal hydride buffer reversibly adsorbs and desorbs hydrogen gas. The change in temperature associated with adsorption or desorption of the hydrogen gas by the metal hydride buffer is thermally communicated to the passenger compartment, thereby conditioning the air therein. Desorbed hydrogen gas is fed back to the fuel cell to power the vehicle. Also provided are a vehicle having a system for conditioning air in a passenger compartment that employs the change in temperature resulting from the adsorption and desorption of hydrogen gas by the metal hydride buffer and methods for heating or cooling a passenger compartment of a fuel cell-powered vehicle.
