An emergency supply system for a transportation means comprises at least one fuel cell, a hydrogen tank, an oxygen tank, an extinguishing agent container, an oxidant supply unit and an extinguishing-agent supply unit. The oxidant supply unit comprises an oxygen inlet that is connectable to the oxygen tank, an air inlet that is connectable to an air source, and an oxidant outlet that is connected to an oxidant inlet of the fuel cell. The oxidant supply unit is adapted either for conveying oxygen from the oxygen inlet or air from the air inlet to the oxidant outlet. The extinguishing-agent supply unit comprises a first extinguishing agent inlet connected to an exhaust air outlet of the fuel cell, a second extinguishing agent inlet connected to the extinguishing agent container, and an extinguishing agent outlet that is connectable to an extinguishing-agent inlet unit of at least one space of the transportation means.
