Embodiment Construction

[0039] Before discussing the method of measuring the amount of hydrogen available in the hydrogen storage container, it is necessary to understand the change of the hydrogen capacity of the hydrogen storage container under real use conditions. The experimental method to meet this requirement is to dehydrogenate the hydrogen storage container that completes the hydrogen charging operation according to the fixed hydrogen charging conditions at various operating temperatures, according to the hydrogen pressure and the minimum hydrogen flow required by the application system. And use the mass flow rate to measure the hydrogen discharge capacity of the hydrogen storage container to obtain the dynamic hydrogen discharge characteristic curve (such as image 3 shown), wherein the curve C1 represents the hydrogen flow value curve, and the curve C2 represents the hydrogen pressure value curve. From this, the effective hydrogen discharge capacity at different operating temperatures can b...

Abstract

A method for measuring out usable residual-hydrogen amount stored in hydrogen container includes fetching service circulation frequency of hydrogen container, fetching hydrogen stock of hydrogen container and consumed hydrogen amount of hydrogen container, then applying calculation formula to calculate out usable residual-hydrogen amount stored in hydrogen container.

Description

technical field [0001] The invention relates to a method for measuring the amount of hydrogen in a hydrogen storage container, in particular to a method for measuring the amount of available residual hydrogen in the hydrogen storage container. Background technique [0002] Whether it is hydrogen engine vehicles, hydrogen fuel cell systems and products, or renewable energy hydrogen production systems, they are all devices that need to use hydrogen storage. The main current commercial hydrogen storage technologies can be divided into three types: liquid state, high-pressure gaseous state and low-pressure metal hydride. In consideration of the safety of use, the storage method of solid metal hydride is more suitable at present. [0003] Generally, solid-state alloy hydrogen storage technology at room temperature and low pressure mostly uses titanium-iron alloy, lanthanum-nickel alloy or magnesium alloy powder as the hydrogen storage medium, and then fills it in a hydrogen stor...
