Abstract
A drive system of an aircraft, including a fuel cell, which can be supplied with hydrogen from a hydrogen tank and with air from a blower, the fuel cell being configured to provide drive power for operational flight after takeoff and before landing dependent on a hydrogen mass flow supplied by the hydrogen tank and dependent on an air mass flow supplied by the blower, and an electrical energy store, which is configured to provide additional drive power for takeoff and landing, wherein an additional hydrogen tank and an air or oxygen tank are configured to interact with the fuel cell such that the fuel cell can be supplied with an additional hydrogen mass flow and with an additional air or oxygen mass flow, thereby compensating at least partially for a loss of the additional drive power provided by the electrical energy store for landing.
