摘要： Proposed are a fuel cell system and a method of controlling the fuel cell system. The fuel cell system may comprise a discharge valve configured to adjust a flow rate between an inlet and an outlet, connected at the inlet to a water trap connected to an anode of a fuel cell stack, and connected at the outlet to an external exhaust line, and a controller configured to derive an error value on the basis of a difference between condensate water production amount and discharge amount of the anode of the fuel cell stack when the discharge valve is in an open state, configured to correct the condensate water production amount of the anode on the basis of the error value when the discharge valve is in a closed state, and configured to open the discharge valve when the corrected condensate water production amount exceeds a predetermined first reference value.

摘要： Provided are electrochemical cells, comprising water-retaining components, and methods of fabricating such electrochemical cells. A water-retaining component is configured to deliver water to the positive active material during the operation of the electrochemical cell. The water-retaining component may be a part of the positive active material layer, a part of the electrolyte layer, and/or a standalone component. In some examples, the water-retaining component comprises one or more crystal hydrates (e.g., MgSO4, MgCl2, Na2SO4, Na2HPO4, CuSO4, CaCl2, KAl(SO4)2, and Mg(NO3)2), one or more water-retaining polymers (e.g., sodium polyacrylate, potassium polyacrylate, ammonium polyacrylate, and a cellulose derivative), one or more inorganic compounds (e.g., fumed silica, precipitated silica). In some examples, a method of forming an electrochemical cell comprises printing a positive active material layer, a negative active material layer, and an electrolyte layer, e.g., printing the electrolyte layer directly over the positive active material layer or the negative active material layer.

摘要： Self-refueling power-generating systems and methods of configuring them are provided, which enable operation in a self-sustained manner, using no external resource for water, oxygen or hydrogen. The systems and methods determine the operation of reversible device(s) in fuel cell or electrolyzer mode according to power requirements and power availability, supply oxygen in a closed circuit, compressing received oxygen in the electrolyzer mode, and supplying water or dilute electrolyte in a closed circuit in conjunction with the closed oxygen supply circuit by separating oxygen produced by the reversible device(s) in the electrolyzer mode from the water or dilute electrolyte received from the reversible device(s). Membrane assemblies may comprise a binder and be hot-pressed to enhance their long-term performance and durability.

摘要： The present disclosure provides a discretization modeling method for electro-osmotic drag effect of water conservation in a fuel cell, comprising: establishing a conservation equation of membrane water in the fuel cell, performing a discretization for a complete electro-osmotic drag effect, obtaining a discretization simulation model of the complete electro-osmotic drag effect based on results of the discretization, solving the conservation equation of membrane water to establish a discretization simulation model of electro-osmotic drag effect of water conservation in the fuel cell. The discretization modeling method for the electro-osmotic drag effect of water conservation in a fuel cell in the present disclosure can perform a discretization and a numerical calculation for a complete electro-osmotic drag effect, the discretization comprising a water conservation portion caused by a membrane water content gradient and a water conservation portion caused by a proton transport flux gradient.

摘要： Methods and systems are described for optimizing water discharge in fuel cell vehicles. The system includes a fuel cell stack, a blower for purging water from the fuel cell stack and a controller. The controller detects that an ambient temperature satisfies a threshold temperature. The controller determines the fuel cell vehicle is approaching a stopping location. The controller calculates a water discharge time prediction necessary to purge excess water from the fuel cell stack while the fuel cell vehicle is operating in response to detecting that the ambient temperature satisfies the threshold temperature and the fuel cell vehicle is approaching the stopping location. The water discharge time prediction is calculated based on the blower operating while the fuel cell stack is in at least one of an idle state and a stopped state as the fuel cell vehicle approaches the stopping location.

摘要： The invention relates to a proton flow reactor for use in storing and releasing energy. In use, a slurry of storage particles in a liquid electrolyte may pass through a first half cell of the proton flow reactor. When the proton flow reactor is in charge mode, protons are bonded or otherwise attracted to the storage particles to form charged storage particles charged with hydrogen, which can hen be stored and/or transported for later use. When the proton flow reactor is in discharge mode, protons are removed from the charged storage particles to fuel an electrochemical reaction, thereby generating electricity. Alternatively, the proton flow reactor in discharge mode can be configured to generate hydrogen gas directly from the in-flowing charged carbon particles.

摘要： A fuel cell system includes a fuel cell, a cathode off-gas discharge channel, a gas-liquid separator, and a cover member. The gas-liquid separator includes a body, a first discharge channel including a first valve seat at an end, and a first valve device including a first valve element and a first driver. The cover member covers at least the first discharge channel and the first valve seat in the gas-liquid separator, and includes a gas channel defining portion that defines a gas channel communicating with the cathode off-gas discharge channel between the cover member and the gas-liquid separator. The gas channel is configured such that a cathode off-gas flowing into the cover member comes into contact with the first discharge channel and the first valve seat and does not come into contact with the first driver.
