  • Patent number: 8798774
    Abstract: Each of the water heaters 1 performs a master and slave setting process that transmits prescribed response data to the other water heaters 1 via a communication line 8 at a timing according to its own identification number and different from those of the other water heaters in a prescribed master and slave setting time period, that sets the water heater itself to slave in a case of receiving the response data from another water heater 1 assigned with an identification number having a priority higher than its own identification number in the master and slave setting time period, and that sets the water heater itself to master in a case of not receiving the response data from another water heater assigned with an identification number having a priority higher than its own identification number in the master and slave setting time period.

  • Patent number: 8445160
    Abstract: An electrolyte membrane on the inside of annular frames with an anode-side electrode catalyst layer, a first gas diffusion layer and a first gas flow channel-forming body stacked on top of the membrane. An electrode catalyst layer, a second gas diffusion layer and a second gas flow channel-forming body are stacked on the underside. Frames have a supply channel supplying fuel gas to the gas flow channel in the first gas flow channel-forming body, a discharge channel discharges the fuel gas. An overhang part that extends outward is on the outer peripheral edge of the first channel-forming body to overlap a flange part of the frame beyond the outer peripheral edge of the anode-side electrode catalyst layer. Penetration of seeping water can be prevented by retaining the seeping water in the overhang part.
