EXHAUST GAS PURIFICATION SYSTEM

摘要

An exhaust gas purification system which purifies exhaust gas discharged from an internal combustion engine includes an exhaust pipe, an electrochemical reactor and a cooler. The exhaust gas flows through the exhaust pipe. The electrochemical reactor is mounted to the exhaust pipe and has a polyelectrolyte membrane. The cooler is provided at a position that is upstream of the electrochemical reactor for cooling the exhaust gas.
