Abstract: Exhaust gas is treated onboard a vehicle. Solar energy is converted into electricity, which is used to power an electrochemical cell mounted onboard the vehicle. Oxygen and hydrogen are produced by the electrochemical cell. Heat and the oxygen produced by the electrochemical cell are provided to a particulate matter filter onboard the vehicle, thereby oxidizing particulate matter disposed on the particulate matter filter.
