A fuel supply arrangement with a fuel supply duct that supplies fuel from a fuel storage reservoir to a fuel cell. The fuel supply duct is between a fuel provision port and a fuel supply port, and a fuel circulation duct is connected to the fuel supply duct to return unconsumed fuel from the fuel cell to the fuel supply duct. A jet nozzle in the fuel supply duct uses negative flow pressure, draws unconsumed fuel from the fuel circulation duct and mixes it into the fuel supply duct. A bypass duct connected to the fuel supply duct bypasses the jet nozzle. A pressure monitoring device monitors pressure in the fuel supply duct and outputs a signal when the pressure drops below a specific value. An activation device activates the bypass duct in response to the signal to bypass the jet nozzle to supply fuel to the fuel cell.
