PURPOSE: To provide a vacuum cleaner which enables continuous application by timely refilling the fuel without a power source cord. CONSTITUTION: An electric blower 2, a fuel cell 3 and a hydrogen cylinder 4 as fuel tank are provided inside the main body 1 of a vacuum cleaner. A hydrogen gas of the hydrogen cylinder 4 is introduced into a hydrogen electrode of the fuel cell 3 by a specified pressure via a conduit 7 while air diffuses into the fuel cell 3 from a filter part 5 to supply oxygen in the air to the oxygen electrode and an electromotive force is generated by an electrochemical reaction in the fuel cell 3 so that power is supplied to the electric blower 2 to make operation ready for cleaning by collecting dust. Casters 8 are mounted on the electric cleaner 1, and the fuel cell 3 and the hydrogen cylinder 4 are built in. This constitution eliminates the need for pulling around a power cord during cleaning while moving. Moreover, continuous use of hydrogen cylinder 4 is enabled by exchanging it for a new cylinder after the hydrogen thereof is consumed up. |
