Combined power generation device comprising wave energy power generation part and fuel cell power generation part

The invention provides a combined power generation device comprising a wave energy power generation part and a fuel cell power generation part. The combined power generation device comprises a dielectric elastomer wave energy power generation part, a seawater electrolysis part, the fuel cell power generation part and a damping plate. The dielectric elastomer wave energy power generation part comprises a buoy body, an upper power generation unit, a lower power generation unit and a moving shaft. Each of the upper power generation unit and the lower power generation unit is composed of conical dielectric elastomers and a fan-shaped electrode. The fuel cell power generation part comprises a packaging structure, a blind end collector plate, a plurality of single cells, a gas port end collector plate, a blind end plate and a gas port end plate. The lower end part of the moving shaft, the seawater electrolysis part, the packaging structure and the damping plate are rigidly connected in sequence. The seawater electr
