Fuel Cell System for an Aircraft and Method for Providing an Inert Gas in an Aircraft

摘要

A fuel cell system for an aircraft includes at least one fuel cell having a first inlet for providing a fuel, a second inlet for providing an oxidant, an outlet for removing exhaust air and a voltage outlet, an electrically operable hydraulic pump, which is integratable into a hydraulics network of the aircraft and connectable to the voltage outlet of the at least one fuel cell and a controllable hydraulic energy converter with changeable operating behaviour. The hydraulic energy converter is adapted for generating such a power demand in the hydraulics network, that the at least one fuel cell provides a predetermined volume flow of oxygen depleted air at the outlet through delivering electrical power to the hydraulic pump.

1. A fuel cell system for an aircraft, the fuel cell system comprising:
at least one fuel cell with a first inlet for supplying a fuel, a second inlet for supplying an oxidant, an outlet for removing exhaust air, and a voltage output; an electrically drivable hydraulic pump integratable into a hydraulic network of the aircraft, and connectable with the voltage output of the at least one fuel cell; and a controllable hydraulic energy converter with variable operating behavior, wherein the hydraulic energy converter is set up to generate the type of power demand in the hydraulic network that the fuel cell dispenses electrical power to the hydraulic pump to provide a prescribed volume flow of oxygen-depleted exhaust air to the outlet.
