Abstract

A magnetohydrodynamic seawater propulsion thruster includes: a first electrode body including a seawater inlet, a seawater flow space, and a seawater outlet; a second electrode body arranged in the seawater flow space to be spaced apart from the first electrode body, and allowing current to flow through the seawater with the first electrode body; a flow guide having a helical shape, arranged between the first electrode body and the second electrode body in the seawater flow space to guide flowing of seawater; a magnetic field formation unit arranged to surround at least a portion of an outer circumference of the first electrode body and generate a magnetic field in an extension direction of the first electrode body; a power supply unit that supplies electricity to the first and second electrode bodies. The power supply unit includes a fuel cell module generating electricity through electrochemical reaction of fuel and oxidizer.
