  • Patent number: 10236521
    Abstract: A fuel cell system is provided that can operate continuously and appropriately when a water self-sustaining operation of the fuel cell system is difficult due to environmental conditions and operating conditions, etc. When a first water level corresponding to a water shortage in a condensed water tank is detected using a water level detector, a controller implements a water-saving mode where the output of a fuel cell is decreased regardless of the external power load and the amount of reforming water used is reduced. When it is determined using a cooling determination device during the water-saving mode that the exhaust gas cooling capability in a condenser brought about by a cooling medium is at least a prescribed value, the controller implements a water recovery mode where the output of the fuel cell is increased regardless of the external power load and the amount of condensed water recovered is increased.

  • Patent number: 10170764
    Abstract: An object is to form a positive electrode active material having small and highly uniform particles by a simple process. A template is formed by forming holes in the template by a nanoimprinting method, and the template is filled with a gel-like LiFePO4 material, whereby small-sized LiFePO4 particles are formed and are used as the positive electrode active material of a secondary battery. The particle size can be reduced to less than 50 nm. Further, when the LiFePO4 particles are sintered, the template may be burned down. By making the particle size of the positive electrode active material smaller than the conventional one, a positive electrode that lithium is injected into and extracted from easily can be manufactured.
