Abstract:
A method of providing anode gas exhaust (38, 39) from a fuel cell stack (36) and carbon dioxide (54) capture by feeding reformed fuel and air into a fuel cell stack (36) where gas exhaust (38, 39) is fed to a series of oxidation/reduction beds (44, 46) to provide exit streams a) of H2O and CO2 (41′) which is fed to a condenser (52) to recover CO2 (54), and b) H2O and CO (48) which is recirculated to the fuel cell stack (36).

Abstract:
A fuel cell system comprises: a fuel generating member that generates a fuel gas by a chemical reaction; a fuel cell part that generates power using the fuel gas supplied from the fuel generating member; a gas passage for circulating the gas between the fuel generating member and the fuel cell part; a circulator that is provided in the gas passage and forces the gas to circulate between the fuel generating member and the fuel cell part; and a circulator control unit that controls the amount of gas circulated by the circulator in accordance with the percentage of non-chemical reaction in the fuel generating member.
Abstract:
A fuel cell apparatus comprises fuel cells, hydrogen generators and a control unit. A fuel cell array comprises a plurality of membrane electrode assemblies (MEAs) each having a major planar surface; the MEAs are arranged such that a first surface of a first MEA which is not a major planar surface of the first MEA faces a second surface of a second MEA which is not a major planar surface of the second MEA. A plurality of fuel cells, for example arranged in an array, are included in a blade, which is connected externally to the control unit. The apparatus can accommodate a plurality of blades. A closed reactor for the generation of hydrogen gas from a chemical hydride comprises a reaction vessel; at least one entry port; and an outlet port for outputting hydrogen gas. A unit form of a composition comprises a chemical hydride; the unit form has a volume of at least 0.01 cm3.
Abstract:
The invention relates to an operating gas system (1a, 1b) for an underwater vehicle, particularly for a submarine or an unmanned underwater vehicle, comprising a fuel cell system (3) and an operating gas container (5) connected in terms of flow to the fuel cell system (3). In order to achieve simple and efficient storage of boil-off gasses (BO), a gas-receiving device (7) is also provided and is connected to the operating gas container. The gas-receiving device (7) contains a sorbent (9, 19) for receiving boil-off gas (BO) from the operating gas container (5). The boil-off gas (BO), which is produced in the operating container (5) with the operating gas (BG) for the fuel cell system and which cannot be consumed directly in the fuel cell reaction, is therefore collected and stored with the aid of the sorbent (9, 19) in the gas-receiving device (7).
Abstract:
A self-regulating gas generator that, in response to gas demand, supplies and automatically adjusts the amount of gas (e.g., hydrogen or oxygen) catalytically generated in a chemical supply chamber from an appropriate chemical supply, such as a chemical solution, gas dissolved in liquid, or mixture. In some embodiments, the gas generator may employ a piston, rotating rod, or other element(s) to expose the chemical supply to the catalyst in controlled amounts. In another embodiment, the self-regulating gas generator uses bang-bang control, with the element(s) exposing a catalyst, contained within the chemical supply chamber, to the chemical supply in ON and OFF states according to a self-adjusting duty cycle, thereby generating and outputting the gas in an orientation-independent manner. The gas generator may be used to provide gas for various gas consuming devices, such as a fuel cell, torch, or oxygen respiratory devices.
