Direct fuel cell based on organic liquid hydrogen storage material

Abstract

The invention relates to a direct fuel cell, and in particular relates to a direct fuel cell based on an organic liquid hydrogen storage material. The direct fuel cell comprises a fuel cell single unit, wherein the fuel cell single unit is connected with a load by an AC / DC conversion circuit. The direct fuel cell is characterized in that a hydrogen storage material outlet on the fuel cell single unit is communicated with a hydrogen storage material tank by a hydrogen storage material output pipe; a hydrogen storage material hydride input hole on the fuel cell single unit is communicated with a hydrogen storage material hydride tank by a hydrogen storage material hydride input pipe; a hydrogen storage material hydride pump is arranged on the hydrogen storage material hydride input pipe; a water outlet on the fuel cell single unit is communicated with a water tank by a water outlet pipe; a gas inlet on the fuel cell single unit is communicated with an oxygen inlet pipe; a gas outlet is arranged at the top of the water tank; and the hydrogen storage material tank is filled with the hydrogen storage material which is multi-element mixed liquid unsaturated heterocyclic aromatic hydrocarbon. The direct fuel cell not only simplifies the devices (has simple structure) but also greatly improves the safety.

Description

technical field [0001] The invention relates to hydrogen energy utilization technology in the field of clean energy and new energy. In particular, it relates to a direct fuel cell based on liquid hydrogen storage materials. That is, for the hydride of a specific liquid hydrogen storage material, it is converted into a hydrogen storage material through a direct fuel cell, and at the same time, electric energy is released. Background technique [0002] Energy is the basis for the survival and development of modern society. The supply capacity of energy is closely related to the sustainable development of the national economy and is one of the strategic foundations of national security. Due to the rapid economic development, traditional non-renewable fossil fuels and other energy sources are becoming more and more urgent. Today's governments are placing their hopes on hydrogen energy, solar energy, wind energy and other emerging energy sources. [0003] Fuel cells are a clean...

Problems solved by technology

Although some solids can be dissolved in a certain solvent, the solvent will reduce its concentration on the electrode surface, such as solids such as phenanthrene and anthracene, and volatile liquids such as benzene cannot be used as their working medium;

[0011] 2) The dehydrogenation temperature of the hydrogenation molecule should not be too high. For example, the dehydrogenation temperature of cyclohexane, a hydrogenation molecule of benzene, is higher than 300°C, which is far beyond the working temperature of the battery and should not be used as a working medium; at the same time, if the dehydrogenation temperature High, the polarization of the anode of the battery is serious, which increases the energy loss in the dehydrogenation discharge

In addition, unstable molecules such as vinyl alcohol cannot be used as a working medium
