Patent number: 10003092Abstract: A fuel cell stack assembly has a plurality of cells each having a fluid coolant conduit. A coolant feed manifold has a first inlet and a second inlet and is coupled to each fluid coolant conduit for distribution of fluid coolant within each cell. A pump is coupled for delivery of fluid coolant to the coolant feed manifold through the first and second inlets. A flow control assembly is configured to periodically modify the relative flow rates of fluid coolant through the first and second inlets so that stagnant regions in the coolant feed manifold are avoided. The flow control assembly may also be adapted to periodically interrupt the flow path between the pump and the manifold such that the fluid coolant is delivered to the manifold intermittently, thereby enabling low water flows below a minimum set point of the pump.Type: GrantFiled: September 16, 2013Date of Patent: June 19, 2018Assignee: INTELLIGENT ENERGY LIMITEDInventors: Ashley James Kells, Pratap Rama, Paul Leonard Adcock, Simon Edward Foster, Jonathan Cole, Emma Farndon

Patent number: 9819033Abstract: A fuel cell power module is coupled to a fuel supply reactor module by way of an adaptor which includes some of the control elements for controlling reaction of reactants in the reactor module. The adaptor includes a housing and a first connection interface in the housing for detachably coupling the adaptor to a fuel cell power module fuel inlet port and a second connection interface in the housing for detachably coupling the adaptor to a reactor module fuel outlet port. A fluid line extends between the first connection interface and the second connection interface. The adaptor includes a motive unit of a flow control mechanism configured to provide motive power to a flow circuit of a reactor module when the reactor module is coupled to the adaptor. The adaptor enables a fuel cell power module to be interfaced with different types of reactor modules having different form factor and different control requirements.Type: GrantFiled: April 15, 2014Date of Patent: November 14, 2017Assignee: Intelligent Energy LimitedInventors: Andrew John Carnall, Simon Nicholas, Ashley James Kells

Patent number: 9450255Abstract: A fuel cell stack assembly has a plurality of fuel cells each having a fluid coolant conduit. A coolant feed inlet manifold has a coolant inlet, and the coolant feed inlet manifold is coupled to each fluid coolant conduit for distribution of coolant to each fuel cell. The coolant feed inlet manifold also has a discharge conduit located at one end of the coolant feed inlet manifold. The discharge conduit is configured to discharge excess coolant from the coolant feed inlet manifold. By supplying excess coolant to the coolant feed inlet manifold problems arising due to very low coolant flow rates through the fluid coolant conduits in the fuel cells can be reduced or eliminated.Type: GrantFiled: September 16, 2013Date of Patent: September 20, 2016Assignee: Intelligent Energy LimitedInventors: Ashley James Kells, Simon Edward Foster, Paul Leonard Adcock, Jonathan Cole
