A thermal management system and method for a fuel cell vehicle is provided. In particular, a radiator, a 3-way valve, a pump, a heater, and a stack are all connected in that order. The system is capable of selectively de-mineralizing and providing an increase in flow rate by connecting a de-mineralizer line to a port at a bypass line side of a 3-way valve.

A cooling system is provided for use with a fuel cell. The cooling system comprises a first heat exchanger fluidly connected to an outlet passage of the fuel cell. The first heat exchanger can be configured to condense at least a portion of a fluid passing through the outlet passage of the fuel cell into liquid water. The cooling system can also comprise a second heat exchanger fluidly connected to an outlet passage of the first heat exchanger and an inlet passage of the fuel cell. The second heat exchanger can be configured to cool a fluid passing into the inlet passage of the fuel cell. In addition, the outlet passage of the fuel cell and the inlet passage of the fuel cell can be fluidly connected to a cathode of the fuel cell, and the inlet passage of the fuel cell can be configured to supply water to the cathode.

A heat exchanger can be integrated into an interconnector that can be used in both a SOFC fuel cell and an EHT electrolyser, which allows a heat-transfer fluid different from that in the reactive and drainage gas circuits to be circulated from the inlet of the reactor, thereby allowing the best possible management of the exothermic operating modes of the SOFC cell and the exothermic or endothermic operating modes of the EHT electrolyser and the SOFC cell, especially in the absence of current for the latter.

A method for manufacturing a heat exchanger includes: providing a porous material that has a porosity of about 30% to about 80%; forming an oxide layer on a surface of the porous material by heat treating the porous material at a temperature in a range of 600° C. to 900° C. for a time period in a range of 8 hours to 12 hours in air; and integrating the porous material into a cold side flow passage of the heat exchanger.

The invention relates to gas analyzers, especially mobile ion mobility spectrometers or mass spectrometers which are operated at atmospheric pressure to detect dangerous substances. The invention uses a fuel cell to generate the electric operating power of the gas analyzer, and the waste heat from the fuel cell is used to regulate the temperature of modules of the gas analyzer.

A heat exchanger cooling system includes: a passage extending from a water tank and branching off into a first passage and a second passage at a branch portion provided in the middle of extension of the passage, the passage including a water discharge portion provided on a distal end side of the first passage so as to face a radiator; a pump configured to send water into the passage from the water tank; a first opening-closing valve provided in the first passage and configured to open and close the first passage; a second opening-closing valve provided in the second passage and configured to open and close the second passage; and a controlling portion configured to control an operation of the pump and to control opening and closing of the first opening-closing valve and the second opening-closing valve.

A fuel cell unit with a plurality of fuel cells defining a longitudinal axis and a main flow direction coaxial to the longitudinal axis. Fuel cell inlets and fuel cell outlets are arranged at opposite ends of the fuel cell unit and in line with the main flow direction. Also, a component comprising first fluid conduits arranged parallel to the main flow direction, the first fluid conduits comprising first fluid inlets and first fluid outlets arranged at opposite ends of the component and in line with the main flow direction. The component is arranged adjacent the fuel cell unit such that at least one of the first fluid inlets and the first fluid outlets of the component are arranged adjacent at least one of the fuel cell outlets and the fuel cell inlets such that a fluid flow may flow substantially parallel to the longitudinal axis of the apparatus in the first fluid conduits of the component and in the fuel cell unit and when passing from the component to the fuel cell unit or vice versa.

The invention relates to a ceramic cooling and heating body for controlling the temperature of components, wherein the cooling and heating body consists of a plate-shaped support with a front side, an opposite rear side and side faces connecting the front side to the rear side, and metallizations, connected to the support, are arranged on the front side and/or the rear side, and the support has cooling elements. In order to be able to control the temperature of any electrical or electronic component, it is proposed according to the invention that a heating structure is affixed to the front side and/or the rear side.
