Unmanned boat for unmanned river survey using energy-independent fuel cell

摘要

The present invention provides an energy independent type fuel cell based unmanned river survey boat, which uses magnesium hydride (MgH_2) materials to produce hydrogen gas for observing and managing water environment of streams, and uses a polymer electrolyte fuel cell using the hydrogen gas as a power source. The present invention comprises: a boat; a hydrogen gas production portion configured at the inside of the boat, and producing hydrogen gas by reacting magnesium hydride (MgH_2) with water; an electric power portion for supplying electric power to the boat using hydrogen produced by the hydrogen gas production portion; and a stream information collection portion installed in the board, and measuring and collecting information about the depth, flow, rate, and water quality of the stream, thereby capable of checking the water quality of the stream while moving without using manpower, and monitoring illegal activities around the stream. In particular, the magnesium hydride (MgH2) materials are used for producing hydrogen gas for observing and managing the water environments of streams, and the hydrogen gas is used in the polymer electrolyte fuel cell as a power source, thereby producing less noise in an environmentally friendly way. In addition, a pressure resistance or heat insulation of a container for storing the produced hydrogen is not required such that the unmanned river survey boat is light and simple.
