摘要： In one aspect, there is disclosed a method of detecting a hydrogen leak in a fuel cell system, including the steps of (a) calculating a mass of hydrogen in a fuel tank, HT new, at a time step, (b) calculating a mass of the hydrogen consumed by the fuel cell at the time step, HFcp new, (c) calculating a total amount of hydrogen that has left the tank from a start to the time step, HTcons, (d) calculating a total amount of hydrogen consumption, HFcpcons, (e) calculating a difference between HTcons and HFcpcons at the time-step, (f) determining if the difference is above a predetermined threshold, and (g) performing an action based on the determination of step (f).

摘要： A wireless based sensor assembly incorporated within a sealed and pressurized vessel including an end plug secured against an inner surface of the vessel. Temperature and pressure sensors are mounted to inner exposed locations of the end plug and are capable of monitoring temperature and a pressure conditions existing within the sealed vessel. A power supply is communicated to the sensors within said vessel and such that the sensors communicate, in wireless fashion, information regarding the conditions existing internally within the vessel to an external location.

摘要： A fuel cell system having a fuel cell with an anode and a cathode wherein both the cathode and anode each have a flow path with an inflow and outflow. A gaseous source containing oxygen is connected to the inflow of the cathode flow path while a gaseous fuel source is connected to the inflow of the anode flow path. Upon shutdown of the fuel cell, a control system reduces the stoichiometric ratio at the anode to less than or equal to one to thereby deplete the oxygen from the gas at the cathode. A normally closed valve is fluidly connected between the cathode outflow and the anode inflow. The control system opens the valve upon shutdown of the fuel cell to thereby purge the fuel from the anode flow path with the oxygen depleted outflow from the cathode flow path.
