METHOD AND SYSTEM FOR CLEANING A CHARCOAL CANISTER OF AN EMISSIONS SYSTEM USING A FUEL CELL

摘要

An evaporative emission control system (26) for a vehicle includes a fuel tank (16), a vapor collection canister (12) in communication with the fuel tank (16) so as to receive hydrocarbons, a fuel cell (28) in communication with the canister (12), and a pump (30) constructed and arranged to pump hydrocarbons from the canister (12) to the fuel cell (28) so that the fuel cell (28) can purge the canister (12) by converting the hydrocarbons to water, carbon dioxide and electricity.
