A marine fuel cell hydrogen supply system based on externally immersed alloy hydrogen storage technology

Abstract

The invention discloses a marine fuel cell hydrogen supply system based on an externally immersed alloy hydrogen storage technology, comprising: a hydrogen storage device includes at least two externally immersed water tanks and at least two sets of alloy hydrogen storage tank groups; The fuel cell body and the first heat exchanger, the first heat exchanger is used to absorb the waste heat of the fuel cell body; at least two sets of hydrogen pipelines, each set of hydrogen pipelines are connected with each set of gold hydrogen storage tanks and are arranged in parallel with each other The hydrogenation pipeline, the first hydrogen outlet pipeline and the second hydrogen outlet pipeline; the circulating liquid pipeline includes a main liquid pipeline, at least two liquid inlet branch pipes, and at least two liquid outlet branch pipes. The marine fuel cell hydrogen supply system adopts the method of supplying hydrogen in parallel with multiple combinations of gold hydrogen storage tanks, which satisfies the principle of single failure of marine equipment, and ensures that the failure of a single combination of gold hydrogen storage tanks will not cause the fuel cell system and the ship to lose power, and The alternate use of multiple sets of gold hydrogen storage tanks can minimize the amount of residual hydrogen to improve hydrogen utilization.

Description

technical field [0001] The invention relates to the field of marine power, in particular to a marine fuel cell hydrogen supply system based on an externally immersed alloy hydrogen storage technology. Background technique [0002] Hydrogen fuel cells are the commanding heights of power energy technology in the 21st century. They have the following advantages: high energy conversion efficiency, low vibration and noise, zero emissions, modular structure, low-cost potential, and compliance with national security and energy strategies. Therefore, green ships using hydrogen fuel cell systems can achieve efficient energy utilization, zero emissions and improved comfort, which is an ideal solution for future green ship power plants. [0003] Although green ships using hydrogen fuel cell technology have the above advantages, the endurance has become a major bottleneck. The core problem restricting the development of long-endurance hydrogen fuel cell ships is that the hydrogen fuel ...
