Title
(EN) Combustion state determining apparatus with catalytic combustion unit and fuel cell
(ZH) 具有催化燃烧单元和燃料电池的燃烧状态判断设备
Abstract
(EN)
An apparatus and method for determining a combustion state includes a catalytic combustion unit for mixing an anode off-gas discharged from a fuel pole of a fuel cell and an oxidizing agent gas, and having a catalytic unit for performing combustion processing. An upstream temperature detecting unit detects a gas temperature at an upstream side of the catalytic unit, and a gas-phase combustion determining unit compares at least one of the gas temperature detected by the upstream temperature detecting unit and a rate of upstream temperature increase with a determining reference value to determine if gas-phase combustion occurs at the upstream side of the catalytic unit.
