  • Patent number: 11569516
    Abstract: A fuel cell system includes a fuel cell stack, a fuel gas supply path, an injector, an ejector, a circulation path, an outlet port pressure detection unit, and a control device. The control device stops driving the injector when an ejector outlet port pressure is equal to or more than a required upper limit value with the injector driven, and drives the injector when the ejector outlet port pressure is equal to or less than a required lower limit value with the injector stopped. The control device reduces the required upper limit value stepwise and reduces the required lower limit value stepwise in a range defined by a first target upper limit value and a second target upper limit value when a required load is varied from a first required load to a second required load and a load reduction amount is more than a first predetermined load.

  • Patent number: 11552324
    Abstract: A flow battery system and methods are provided for eliminating crossover issues of active materials in redox flow batteries. A solid adsorbent with large specific surface area is disposed in an electrolyte of at least one half-cell, in contact with the electrolyte. During a charging process, the active material in a charged state is captured and stored on surfaces of the adsorbent, so that concentrations of the active material in the electrolyte in the charged state is reduced and the crossover is inhibited. During a discharging process, the active material is desorbed from the adsorbent to the electrolyte and pumped into the stack for reaction. The flow battery stack can have a microporous membrane separator. The electrolyte of the flow battery includes zinc iodide as active material and polyethylene glycol (PEG) as an additive.
