    Abstract: Reduced emissions of nitrogen oxides can be achieved if engines are fuelled with mixtures of gaseous fuels such as hydrogen and natural gas. Storing the gaseous fuels separately is desirable so that the fuel mixture ratio can be changed responsive to engine operating conditions. The present apparatus increases the storage density of gaseous fuels such as hydrogen by storing them in gaseous form at high pressures and at sub-ambient temperatures. A first thermally insulated space for holding a first gaseous fuel in a liquefied form is separated from a second thermally insulated space for holding a second gaseous fuel by a thermally conductive fluid barrier. The second gaseous fuel liquefies at a lower temperature than the first gaseous fuel such that the second gaseous fuel can be stored within the second thermally insulated space in a gaseous form at a sub-ambient temperature.

    Abstract: An electrochemically active hydrogen diffusion barrier which comprises an anode layer, a cathode layer, and an intermediate electrolyte layer, which is conductive to protons and substantially impermeable to hydrogen. A catalytic metal present in or adjacent to the anode layer catalyzes an electrochemical reaction that converts any hydrogen that diffuses through the electrolyte layer to protons and electrons. The protons and electrons are transported to the cathode layer and reacted to form hydrogen. The hydrogen diffusion barrier is applied to a polymeric substrate used in a storage tank to store hydrogen under high pressure. A storage tank equipped with the electrochemically active hydrogen diffusion barrier, a method of fabricating the storage tank, and a method of preventing hydrogen from diffusing out of a storage tank are also disclosed.
