A 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 embedded alloy hydrogen storage technology, comprising: at least two sets of alloy hydrogen storage tank groups, each group of gold hydrogen storage tank groups has at least one alloy hydrogen storage tank, and each alloy hydrogen storage tank group has at least one alloy hydrogen storage tank. A gas storage cavity and a liquid storage cavity are formed inside the hydrogen storage tank; the fuel cell module includes a fuel cell stack and an expansion water tank that are connected and can both heat the liquid; at least two sets of hydrogen pipelines, each set of hydrogen pipelines includes The hydrogenation pipeline, the first hydrogen outlet pipeline and the second hydrogen outlet pipeline are connected with each gas storage chamber of each gold hydrogen storage tank group and are arranged in parallel with each other; the circulating liquid pipeline includes the main liquid of the circulating circuit. 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 sets of gold hydrogen storage tanks, so that the alternate use of multiple sets of gold hydrogen storage tanks can minimize the amount of residual hydrogen and improve the utilization rate of hydrogen.

Description

technical field [0001] The invention relates to the technical field of marine power, in particular to a marine fuel cell hydrogen supply system based on an 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 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 s...
