Marine fuel cell hydrogen supply system based on embedded alloy hydrogen storage technology

Abstract

The invention discloses a marine fuel cell hydrogen supply system based on an embedded alloy hydrogen storage technology. The system comprises at least two alloy hydrogen storage tank groups, a fuel cell module, at least two groups of hydrogen pipelines, and a circulating liquid pipeline; each alloy hydrogen storage tank group is provided with at least one alloy hydrogen storage tank, and a gas storage cavity and a liquid storage cavity are formed in each alloy hydrogen storage tank; the fuel cell module comprises a fuel cell stack and an expansion water tank which are connected with each other and can heat liquid; 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 gas storage cavity of each alloy hydrogen storage tank group and are arranged in parallel; and the circulating liquid pipeline comprises a main liquid pipeline which is a circulating loop, at least two liquid inlet branch pipes and at least two liquid outlet branch pipes. According to the marine fuel cell hydrogen supply system, a mode that multiple alloy hydrogen storage tank groups are connected in parallel to supply hydrogen is adopted, so that the amount of residual hydrogen can be reduced to the greatest extent by alternately using the multiple alloy hydrogen storage tank groups, and the hydrogen utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of ship power, in particular to a ship fuel cell hydrogen supply system based on embedded 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-mentioned advantages, endurance has become a major bottleneck. The core problem restricting the development of long-endurance hydrogen fuel cell ships is that the hydrogen fuel st...
