Abstract: A capacitor bank for an electrical power generator comprises: a positive assembly having a positive electrical terminal; a negative assembly having a negative electrical terminal; at least one capacitor sandwiched between and electrically coupled to the positive and negative assemblies; and electrical interconnects coupled to each of the terminals and for coupling to a load or to another capacitor bank. The positive and negative assemblies of the capacitor bank are each stackable on the positive and negative assemblies of another capacitor bank. When two capacitor banks are stacked with their positive assemblies facing each other, the interconnects couple the capacitor banks in series, and when two capacitor banks are stacked with a positive assembly facing a negative assembly, the interconnects couple the capacitor banks in parallel.

Abstract: A fuel cell power pack comprises a base module, a ballast module, a fuel supply module, a generator module and an enclosure consisting in part of panels, that is shaped to fit within the battery bay of an electric vehicle. The base and ballast modules are configured to provide ballast for the electric vehicle, to hold the fuel supply module, and to form part of the power pack enclosure. The fuel supply module comprises a fuel storage cylinder and a length-minimized fuel supply assembly to provide a maximized fuel supply to the generator module. The generator module comprises a fuel cell stack and balance of plant components operable to generate electricity. An explosion dissipation structure is provided on at least one enclosure panel.

Abstract: A fuel cell fluid management system that transfers water vapor from a fuel cell stack's oxidant exhaust to the fuel cell stack's fluid supplies through membrane tubes; that coalesces and separates liquid water from the fuel cell's fluid exhaust streams for removal to the environment; that transfers heat from the fuel cell stack to the fluid supplies, and that disposes of purged fuel cell fuel. The fluid management system is shaped to close couple to the fluid ports of a corresponding fuel cell stack.

Abstract: A fuel cell fluid dissipater dissipates excess air, water and unreacted fuel from a fuel cell and comprises a gas permeable and water absorbing dissipation media and a fluid intake assembly. The fluid intake assembly directs excess water and unreacted fuel and air from the fuel cell to the dissipation media where the excess water is directed to a bottom portion of the dissipation media and where the unreacted fuel and air are directed to a top portion of the dissipation media. An air stream is directed through the dissipation media such that the excess water and unreacted fuel and air in the media are dissipated to the environment.

Abstract: A fuel cell system comprises a fuel cell having an anode and a cathode, a fuel feed line connected to the anode, an oxidant feed line connected to the cathode and a cathode exhaust line. A water collecting unit is connected to the cathode exhaust line, and a cooling circuit comprising a radiator is configured to cool the fuel cell. A nozzle is connected to the water collecting unit and configured to spray water onto the radiator.

Abstract: A device is provided for filling a tank with a combustible medium from storage container. Supply means are disposed on the side of the storage container and receiving means are disposed on the side of the tank for introducing the medium into the tank. The supply means and the receiving means include closing means. The device further includes potential equalization means for equalizing an electrical potential between the storage container and the tank. The potential equalization means are arranged on the supply means or on the receiving means so that when the supply means move towards the receiving means, the potential equalization means can be forced into electrical contact with the housing of the tank. When the supply means subsequently come even closer to the chassis, the potential equalization means unlocks the closing means disposed on the supply means and/or the receiving means.
