摘要： A manifold plate for a fuel cell including a plurality of openings for leading reactants towards and/or away from the fuel cell and at least one magnet providing a magnetic field which is oriented in a direction of the stack of the fuel cell. The manifold plate defines a main direction which may be seen as in a direction of a stack including electrodes forming the fuel cell. The openings of the manifold plate may be arranged along the main direction of the manifold plate and the magnet of the manifold plate may be arranged between two of the openings and may be oriented so that the direction between north pole and south pole of the magnet corresponds to the main direction.

摘要： An aircraft includes a fuel cell system including a fuel cell powered by hydrogen received from a supply of hydrogen, and a propulsion unit including a conduit through which a flow of air is propelled. A first heat exchanger transfers heat from the fuel cell to a coolant fluid located in a coolant loop, and a second heat exchanger is located in the conduit for heating the air passing through the conduit by transferring heat to the air from the coolant fluid via the second heat exchanger. This configuration serves to cool the fuel cell while increasing the efficiency of the propulsion unit.

摘要： An aircraft propulsion system includes an energy conversion device that uses a cryogenic fuel and air to generate power and thermal energy, and a bottoming cycle where a working fluid is circulated within a closed circuit that includes a bottoming compressor section and a bottoming turbine section. A primary heat exchanger provides thermal communication of thermal energy from the energy conversion device to the working fluid of the bottoming cycle. A second heat exchanger is in thermal communication with the working fluid and a heat source other than from the energy conversion device for changing a temperature of the working fluid flow.

摘要： An electric vehicle propulsion system includes an electric motor and a battery pack formed as a single, integrated unit. It is a self-contained, integrated electric propulsion system. It disrupts the long-established engineering paradigm that the electric motor and the battery pack have to be designed, built and installed as separate systems.

摘要： A component for an aircraft and an aircraft with such component. The component includes a heat source enclosed by a housing, heat exchanger, heat sink, at least one structural suspension element, and an air duct. Each structural suspension element is attached to an inner surface of the housing and supports one or more of the heat source within the housing. The heat sink is part of the housing and configured to guide air from an inside of the housing an outside of the housing. Each heat exchanger is thermally coupled to the heat source. Each heat exchanger is fluidly connected to the heat sink via an inlet line and a return line for a coolant. The air duct is configured to guide ambient air from the outside through the housing, past each of the at least one structural suspension element, and through the heat sink out of the housing.
