Marine fuel cell hydrogen supply system based on external immersion type alloy hydrogen storage technology

Abstract

The invention discloses a marine fuel cell hydrogen supply system based on an external immersion type alloy hydrogen storage technology. The system comprises a hydrogen storage device, wherein the hydrogen storage device comprises at least two external immersion tanks and at least two groups of alloy hydrogen storage tank groups; a fuel cell module which comprises a fuel cell body and a first heat exchanger which are connected, wherein the first heat exchanger is used for absorbing waste heat of the fuel cell body; at least two groups of hydrogen pipelines, wherein each group of hydrogen pipelines comprises a hydrogenation pipeline, a first hydrogen outlet pipeline and a second hydrogen outlet pipeline which are communicated with each group of alloy hydrogen storage tank group and are arranged in parallel; and the circulating liquid pipeline comprises a main liquid pipeline, at least two liquid inlet branch pipes and at least two liquid outlet branch pipes. The fuel cell hydrogen supply system for the ship adopts a mode of parallel hydrogen supply of the multiple groups of alloy hydrogen storage tank groups, meets the principle of single failure of marine equipment, ensures that the fuel cell system and the ship cannot lose power after the single group of alloy hydrogen storage tank group fails, and can reduce the residual hydrogen amount to the greatest extent by alternately using the multiple groups of alloy hydrogen storage tank groups, so that the hydrogen utilization rate is improved.

Description

Technical field [0001] The present invention relates to the field of power ships, more particularly to a hydrogen absorbing alloy on the outer immersion technique bunker fuel cell hydrogen supply system. Background technique [0002] Hydrogen fuel cell technology is the commanding heights of power and energy in the 21st century, has the following advantages characteristics: high energy conversion efficiency, low vibration and noise, zero emissions, modular structure, low-cost potential, consistent with national security and energy strategy. Thus, the fuel cell system using the hydrogen green ship can achieve efficient use of energy, zero emissions and enhance comfort, it is the ideal solution for the next green ship power plant. [0003] Although the use of hydrogen fuel cell technology green ship has the above advantages, but endurance become a major bottleneck. The core problem restricting the development of ship long endurance hydrogen fuel cell is hydrogen storage density of ...
