Abstract: According to one embodiment, a fuel cell system supplies high-pressure oxygen to a fuel cell by a compressor unit in which a compressor and a turbine are interlocked. An oxygen-containing gas flowing out from an oxygen-containing gas flow path flows into a cooling water tank and then is discharged. Cooling water is supplied from the cooling water tank to a cooling water flow path in the fuel cell.

Abstract: A method is provided to optimize the surface of a carbon electrode for flow battery. A reaction solution is prepared as containing a requested ratio of functional group. After spraying the reaction solution on the carbon electrode, a number of related parameters of an atmospheric plasma are set for activation the carbon electrode. Thus, the functional group is covalently bonded on the surface of the carbon electrode according to requirement. Thereby, an accurate control of the type and number of the functional group bonded on the surface of the carbon electrode is achieved with the stability and performance of flow battery further enhanced.

Abstract: A fuel supply arrangement with a fuel supply duct that supplies fuel from a fuel storage reservoir to a fuel cell. The fuel supply duct is between a fuel provision port and a fuel supply port, and a fuel circulation duct is connected to the fuel supply duct to return unconsumed fuel from the fuel cell to the fuel supply duct. A jet nozzle in the fuel supply duct uses negative flow pressure, draws unconsumed fuel from the fuel circulation duct and mixes it into the fuel supply duct. A bypass duct connected to the fuel supply duct bypasses the jet nozzle. A pressure monitoring device monitors pressure in the fuel supply duct and outputs a signal when the pressure drops below a specific value. An activation device activates the bypass duct in response to the signal to bypass the jet nozzle to supply fuel to the fuel cell.

Abstract: Aspects of integrated hydrogen fuel cell injection units herein use additive manufacturing to form a single part. A space between a body and an ejector nozzle/venturi tube system forms an attenuation volume. The heat exchanger is integrated within the attenuation volume, saving space. The ejector nozzle/venturi tube, and the stack anode inlet to the fuel cell, are arranged through the heat exchanger and allow an injector at the base of the body to selectively emit hydrogen into the anode of the fuel cell. This architecture obviates the need for many O-rings and bolts used in present fuel injection systems using existing manufacturing techniques that may be unduly large and unwieldy and that may cause hydrogen leakage at different connection points.
