摘要： The fuel cell system includes: at least one fuel cell adapted to generate electrical energy from a fuel gas and an oxidizer gas; a fuel feed duct provided for supplying the fuel cell with fuel gas, the fuel feed duct including an upstream part and a downstream part; a Venturi effect ejector including a high pressure inlet, a low pressure inlet and an outlet, the upstream part of the fuel feed duct being connected to the high pressure inlet of the ejector and the downstream part extending between the ejector outlet and the fuel cell; an off-gas recirculation duct extending between the fuel cell and the low pressure ejector inlet so that, in the presence of a stream of fuel gas coming from the upstream part of the fuel feed duct and passing through the ejector, the ejector draws up off-gas from the recirculation duct and ejects it into the downstream part mixed with the stream of fuel gas coming from the upstream part; a control circuit and a valve arranged in the upstream part of the fuel feed duct and arranged to be controlled by the control circuit, the valve being adapted to be placed in an open state, in which it lets the stream of fuel gas from the upstream part pass through the ejector, or in a closed state, in which no stream of gas from the upstream part can flow through the ejector. characterized in that said control circuit is arranged to place the valve alternately in the open state and then the closed state, so that the stream of fuel gas passing through the ejector is intermittent, being frequency and/or pulse width modulated by the control circuit.

摘要： A fuel cell system that employs a technique for safely removing hydrogen gas that accumulates within a cooling fluid reservoir. The fuel cell system includes a fuel cell stack and a compressor for providing airflow to the cathode side of the fuel cell stack. The system also includes an air filter box having an air filter that is in fluid communication with an air pocket in the reservoir. The air intake to the compressor flows through the air filter box, and sucks the gas from the reservoir, which is then sent to the cathode side of the fuel cell stack to be converted to water by the electro-chemical reaction therein.

摘要： A device and method to convert residual hydrogen present in a fuel cell cooling system into water. An oxygen-bearing fluid is supplied to the cooling system from a source that also has elevated moisture levels to minimize the likelihood that the oxygen-bearing fluid will dry out or otherwise deplete the coolant in the cooling system. One or more valves are included to avoid the formation of adverse pressure gradients that could inhibit the continued supply of the oxygen-bearing fluid to the cooling system.
