Control device of gas sensor

摘要: When the ignition switch of a vehicle is turned OFF, purging process for increasing flow an off-gas fluidizing in each outlet side pipings fuel cell and discharging water remaining system to outside started be executed, amount current conductance heater gas sensor increased synchronously with start execution process. With completion process, fluidization stops, units (for example, electrifying voltage) gradually decreased depending on predetermined reducing which preset, thereby stopping decreased, heater.
