摘要： A system is disclosed for providing inerting gas to a protected space, and also providing electrical power. The system includes an electrochemical cell comprising a cathode and an anode separated by a separator comprising a proton transfer medium. Inerting gas is produced at the cathode. A fuel source comprising methanol or formaldehyde or ethanol and a water source are each in controllable operative fluid communication with the anode. A controller is configured to alternatively operate the system in a first mode of operation where water is directed to the anode fluid flow path inlet and electric power is directed from a power source to the electrochemical cell, and in a second mode of operation in which the fuel is directed from the fuel source to the anode fluid flow path inlet and electric power is directed from the electrochemical cell to the power sink.

摘要： A direct liquid fuel cell power generation device comprises a direct liquid fuel cell system and a low-temperature auxiliary starting component. A heat exchanger is arranged at a stack cathode inlet. The heat of a fuel solution at a stack anode outlet is used to heat the air. The heat generated by an electronic load for starting is used to heat a condenser. The heat of a methanol solution at a liquid outlet of a gas-liquid separator is used to preheat high-concentration fuel flowing into a refueling pump. Starting and operation in a low-temperature environment can be realized through auxiliary heating of external power supplies such as the low-temperature auxiliary starting component or an in-vehicle cigarette lighter. Organic micromolecule substances such as methanol and ethanol are used as fuel and are subjected to catalytic combustion in a catalytic combustor.

摘要： A fuel cell anode flow field includes at least one flow channel with a cross-sectional area that varies along at least a portion of its length. In some embodiments, the channel width decreases along at least a portion of the channel length according to a natural exponential function. This type of anode flow field can improve performance, reduce fuel consumption and/or reduce detrimental effects such as carbon corrosion and catalyst degradation, thereby improving fuel cell longevity and durability. When operating the fuel cell on either a substantially pure or a dilute fuel stream, this type of anode flow field can provide more uniform current density. These flow channels can be incorporated into reactant flow field plates, fuel cells and fuel cell stacks.

摘要： A fuel cell arrangement for carrying out a method for ascertaining the overvoltage of a working electrode in a fuel cell, in which the potential of a reference electrode compared to the grounded counter electrode is measured. For the measurement, a fuel cell comprising a polymer electrolyte membrane is used, in which the counter electrode comprises a lateral edge having at least one convexly curved region, and the electrolyte membrane surface, adjoining the counter electrode, comprises an electrode-free region in which the reference electrode is disposed on the electrolyte membrane surface. In contrast, the working electrode is continuous, which is to say has a large surface. The minimum distance Lgap between the reference electrode and the edge of the counter electrode Lgap=3×Ll,r with (a) and (b), where m=ionic conductivity of the electrolyte membrane (Ω−1 cm −1), box=Tafel slope of the half cell for the electrochemical reaction of the working electrode, lm=membrane layer thickness (cm) and jox0=exchange current density of the catalyst of the working electrode per unit of electrode surface in (A cm−2). This arrangement can advantageously be used to ensure that the potential measured at the hydrogen-fed reference electrode corresponds to the overvoltage of the working electrode with sufficient accuracy. The method can be applied to polymer electrolyte membrane fuel cells (PEMFC), to direct methanol fuel cells (DMFC) or to high-temperature fuel cells (SOFC).

摘要： A mass spectrometry-based method of directly online detecting fuel cell reaction products includes passing a reactant sample (16) through a fuel cell (12) to form reaction products that exit the fuel cell (12) in an output stream (26). The method also includes adding a derivatizing reagent (32) to the output stream (28) to form a derivatized output stream (34), wherein the derivatizing reagent (32) reacts with a potential reaction product to thereby form a derivatized reaction product if the potential reaction product is present. The method further includes directing a charged solvent (44) toward the derivatized output stream (34) to thereby ionize the derivatized output stream (34) and directing the ionized, derivatized output stream (54) to a mass spectrometer (14), the mass spectrometer (14) being configured to detect the derivatized reaction product.
