Removable plate-shaped battery series battery pack structure

Abstract

The invention discloses a removable plate-shaped battery series battery pack structure. The removable plate-shaped battery series battery pack structure comprises a heat and pressure keeping shell, a single battery integration unit, a fuel gas distributing unit, an oxidation gas distributing unit, a conductive unit and a battery fastener; the single battery integration unit is formed by serially integrating at least two single batteries, a metal screen and the fastener; the single batteries (1-2-1) are sequentially superposed, and the single batteries physically contact with each other through the metal screen; the single battery integration unit is arranged in the heat and pressure keeping shell; the positive electrode and the negative electrode of the single battery integration unit are lead out of the heat and pressure keeping shell through the conductive unit; and the fuel gas distributing unit and the oxidation gas distributing unit are used for supplying a fuel gas and an oxidation gas to the single battery integration unit. The removable plate-shaped battery series battery pack structure considers the removability of single batteries and the sealing performance of the batteries, and effectively solves the problems of uneven battery pressure, large battery constraining pressure and difficulty in maintenance of a battery pack in the prior art. The above design idea of the cell pack structure is also suitable for a solid oxide electrolytic tank pack structure.

Description

technical field [0001] The invention relates to the technical field of energy production, in particular to a series battery stack structure of removable plate-shaped batteries. Background technique [0002] A fuel cell is an electrochemical device that directly converts the chemical energy of reactants into electrical energy, and consists of an anode, an electrolyte, and a cathode. It can be divided into five categories: alkaline fuel cells, phosphate fuel cells, molten carbonate fuel cells, proton exchange membrane fuel cells and solid oxide fuel cells. As a new generation of fuel cells, solid oxide fuel cells are considered to be a promising energy conversion device. Solid oxide fuel cells have the following advantages: the energy efficiency per unit volume and the energy density per unit volume are relatively high, and high-power and high-efficiency power generation can be realized. If combined heat and power supply, the energy conversion efficiency can reach more than 8...
