A fuel cell system for an aircraft includes a hydrogen burner, an oxidizing agent, and a fuel cell. The hydrogen burner has a first inlet suitable for receiving a first oxidizing agent, a second inlet capable of receiving at least hydrogen, and an outlet suitable for delivering a second oxidizing agent and heat. The oxidizing agent conditioning system has an inlet and an outlet, said inlet being suitable for receiving the second oxidizing agent and heat, said outlet being capable of delivering the conditioned second oxidizing agent. The fuel cell has an anode and a cathode, the cathode has a cathode inlet connected to the outlet of the oxidizing agent conditioning system, the cathode inlet receiving the conditioned second oxidizing agent.

Fuel cell system

Embodiments of the present invention provide a single coolant loop () that can be used for cooling at least two systems () that are generally operable at two different temperatures. Rather than providing two separate cooling loops that can provide the two different cooling temperatures, there is provided a single cooling loop () that can route, harness, and mix heated coolant so that the two system can be served by a single loop.

Fuel cell system with a single coolant loop

Embodiments of the present disclosure relate generally to the use of the fuel cell systems on board aircraft and other passenger transportation vehicles and to methods of using heat, air, and water generated by such fuel cell systems. The heat may be used to address condensation within the aircraft. The heat may be used to help evaporate excess water that would otherwise condense in the aircraft skin. The excess water collected may be used to create humidification for cabin air. In other examples, the heat, warmed air, or warmed water may be delivered to other locations or heating systems for beneficial use.

Aircraft fuel cell heat usages

Described are inerting systems that may be used on board an aircraft or other passenger transportation vehicle to reduce a risk of fire due to electronic components or to other elements in a compartment and to assist in preventing or extinguishing any fire or hazardous condition that may occur. The systems include a source of inert gas such as oxygen depleted air generated from a fuel cell on board the aircraft. The oxygen depleted air or other inert gas is conveyed through ducts to compartments that house the electronics, thus changing the conditions in the compartment to be less conducive to fire.
