Fuel cell system and control method therefor

A fuel cell system includes an accumulated current value measuring unit. The accumulated current value measuring unit measures an accumulated current value by time integration of current output from the fuel cell in a period during which oxygen is produced by water-splitting reaction in an anode of a negative voltage cell. A control unit uses a first correlation between the accumulated current value in the oxygen generation period and an oxygen consumption rate in the anode and a second correlation between a current density of the fuel cell in the oxygen generation period and an oxygen production rate in the anode to obtain a current density at or below which the amount of oxygen in the anode may be reduced, and causes the fuel cell to output electric power at a current density lower than the obtained current density.

Water feeder controller for boiler

A water feeder controller for a boiler monitors a low water cutoff sensor in a boiler and uses a feed timer to feed water to the boiler for a predetermined feed period of time. The feed timer brings the water level in the boiler well above the low water cutoff sensor. The feed timer supplies water to the boiler only if the low water cutoff sensor continues to indicate a low water level for a delay period of time measured by a delay timer. A resettable display indicates the quantity of water supplied by the water feeder to the boiler based on a feed counter incremented during water feeding. A manual feed button allows water to be manually fed to the boiler. The quantity of water manually supplied to the boiler is also shown on the display. The feed timer and delay timer are preferably implemented in software in a microcontroller in the water feeder controller. A lockout loop in the software prevents overfeeding of water to the boiler in the event of a failure of the low water cutoff sensor.

Method of detecting and correcting relay tack weld failures

A method of detecting and attempting to correct a relay tack weld failure of its contacts is presented. This method senses the failure of a relay's contacts to open once it has been commanded to trip. This sensing may directly sense relay conditions, or may indirectly determine the failure by sensing a system parameter that shows the effects of the failure. Once the failure of the relay to open has been determined, the relay is again energized in an attempt to break loose the relay tack weld. If the relay fails to open after this first attempt, the relay may again be repulsed. Preferably a relay check timer is utilized to ensure that the system has stabilized before a repulse is attempted. A relay pulse timer may be used to control the pulse duration during these attempts. The number of attempts may also be limited.

Electronic condensate overflow switch

A non-polarized electronic condensate overflow switch uses microprocessor-controlled low-resistance MOSFETs to connect and disconnect power to an HVAC system. The condensate overflow switch derives operational power directly from an AC main and does not need an external power supply or a separate, reference ground line, and therefore does not require configuration in a particular polarity. The microprocessor controls the turning on and off of the power MOSFETs as needed when condensate overflow is detected and also provides more efficient sensing of condensate overflow and other operations, thus minimizing the power needed by the condensate overflow switch. Such a non-polarized electronic condensate overflow switch may be installed within a drain pan, in line with an outlet of the drain pan, or at a remote location away from the drain pan.
