A controller is coupled to the fuel cell stack, the energy storage device, and the load device via a communications connection. The controller obtains information relative to an operation of at least one of the fuel cell stack and the energy storage device and the controller controls an operation of the load device based on the information.
Fuel cell system, use of a fuel cell system and aircraft with a fuel cell system
A fuel cell system includes a fuel cell having a housing that encases the fuel cell, a supply line for a fuel cell fuel, and an exhaust gas line for fuel-cell exhaust gas. In this arrangement the supply line extends in the exhaust gas line, and the exhaust gas line encases the supply line while forming a space. Any leakage in the supply line thus results in the fuel being flushed out by means of the exhaust gases flowing in the exhaust gas line so that higher system reliability and a reduction in costs can be achieved.
Interconnect and end plate design for fuel cell stack
Various embodiments include interconnects and/or end plates having features for reducing stress in a fuel cell stack. In embodiments, an interconnect/end plate may have a window seal area that is recessed relative to the flow field to indirectly reduce stress induced by an interface seal. Other features may include a thicker protective coating and/or larger uncoated area of an end plate, providing a recessed portion on an end plate for an interface seal, and/or recessing the fuel hole region of an interconnect relative to the flow field to reduce stress on the fuel cell. Further embodiments include providing intermittent seal support to minimize asymmetric seal loading and/or a non-circular seal configuration to reduce stress around the fuel hole of a fuel cell.
