    摘要: A fuel cell system is provided, including an HFR measurement device in electrical communication with a fuel cell stack. The HFR measurement is used online to measure an HFR of the fuel cell stack suitable for calculation of a d(HFR)/d(RH) ratio. A humidity regulator is provided in fluid communication with the fuel cell stack. A controller periodically changes stack operating conditions to perturb an RH of the fuel cell stack, process the HFR response, and compute the d(HFR)/d(RH) ratio. A method for online identification and control of the fuel cell stack humidification is also provided. The d(HFR)/d(RH) ratio is an auxiliary measurement of membrane hydration which is used as a feedback for hydration control.

    摘要: A fuel cell includes a cathode having an air flow field. An anode includes an inlet and an outlet for providing unused fuel to a fuel recycling line. A pressure regulator is arranged upstream from an ejector and communicates with the air flow field for adjusting a fuel pressure at the motive inlet in response to an air pressure associated with the air flow field. The cathode and/or anode includes a porous water transport plate adjacent to the air flow field and/or fuel flow field respectively. A back pressure valve is arranged downstream from the air flow field for producing an air back pressure that generates a desired differential pressure across the water transport plate. The back pressure valve is controlled to achieve the desired differential pressure across the water transport plate so that the fuel cell maintains water balance.

    摘要: Moisture caused by humidity in the fuel gas and water vapor from the water that is generated become condensed inside of the fuel cell when power generation in the fuel cell is temporarily stopped, making it necessary to prevent obstruction to the fuel gas flow channel when power generation is restarted. A fuel cell is configured so that it overlaps with a single cell comprised of an electrolyte membrane sandwiched between a fuel electrode and an oxidant electrode. Oxidant supply means 202 supplies oxidant to the oxidant electrode in the fuel cell. Exhaust fuel circulation means 205 resupplies the fuel emitted from the fuel electrode of the fuel cell back to the fuel electrode. When requested power generating capacity 201 for the fuel cell is less than the prescribed power generation capacity, oxidant supply means 202 temporarily stops the oxidant supply, while exhaust fuel circulation means 205 continues to operate and circulate the fuel, in order to prevent obstruction in the fuel flow channel due to water condensation caused by humidity or water vapor so that when the temporary stop is released and the system is restarted, a reliable fuel supply becomes possible.

    摘要: The present disclosure generally relates to an on-demand hydrogen gas generation device, suitable for use in a fuel cell, which utilizes water electrolysis, and more particularly galvanic cell corrosion, and/or a chemical hydride reaction, to produce hydrogen gas. The present disclosure additionally relates to such a device that comprises a switching mechanism that has an electrical current passing therethrough and that repeatedly and reversibly moves between a first position and a second position when exposed to pressure differential resulting from hydrogen gas generation, in order to (1) alter the rate at which hydrogen gas is generated, such that hydrogen gas is generated on an as-needed basis for a fuel cell connected thereto, and/or (2) ensure a substantially constant flow of hydrogen gas is released therefrom. The present disclosure additionally or alternatively relates to such an on-demand hydrogen gas generation device that comprises a gas management system designed to maximize the release or evolution of hydrogen gas, and in particular dry hydrogen gas, therefrom once it has been formed, thus maximizing hydrogen gas output. The present disclosure is still further directed to a fuel cell comprising such an on-demand hydrogen gas generation device, and in particular a fuel cell designed for small-scale applications.
