A blowing system includes: a first blowing unit including a first body that houses a first fan and includes a first air outlet for blowing-out wind from the first fan; a second blowing unit including a second body that houses a second fan, includes a second air outlet for blowing-out wind from the second fan, and has a shape that is in two-fold symmetry with the first body; and a first connection that rotatably-connects an edge on a back face-side of a first side face of the first body and an edge on a back face-side of a second side face of the second body so that an angle formed by the first and second bodies is variable. The first and second blowing units come into contact at three or more points, and the directions of respective rotation axes of the first and second fans cross at a predetermined angle.

Lifetime required of mobile-use fuel cells is secured and prolonged, stabilized pump performance is maintained by preventing bearing seizure and abnormal wear. The shaft () of a pump mechanism section () and the shaft () of a motor section () are integrated, and the shafts () are supported by two or more ball bearings disposed in the pump mechanism section (), thereby making it possible to fill grease in the closed spaces of the ball bearings (), and secure a sufficient lifetime basically with almost no possibility of the grease leaking out, even if it is used at a relatively high environmental temperature.
