[0056]下面结合实施例与附图对本发明作进一步详细描述，需要指出的是，以下所述实施例旨在便于对本发明的理解，而对其不起任何限定作用。

[0057]图1-4中的附图标记为：阳极层1、第一电解质层21、第二电解质层22、第一阴极层31、第二阴极层32、第一开口端41、第二开口端42、第一阳极盖板51、第二阳极盖板52、阳极外侧密封层53、第一阴极盖板61、第二阴极盖板62、阳极层的第一侧面71、阳极层的第二侧面72、盖板第一部分521、盖板第二部分522、注射器8、封装螺栓9、电池10、中空通道11、橡胶密封垫12。

[0058]本实施例中，固体氧化物燃料电池采用对称双阴极结构，即，固体氧化物燃料电池以阳极层1为支撑层，呈上下分布结构，具体是：阳极层1、电解质层以及阴极层沿厚度方向上下层叠，电解质层包括第一电解质层21与第二电解质层22，第一电解质层21位于阳极层1的上表面，第二电解质层22位于阳极层1的下表面；阴极层包括第一阴极层31与第二阴极层32，第一阴极层31位于第一电解质层21的上表面，第二阴极层32位于第二电解质层22的下表面。阳极层1设置若干条用于燃料气体流通的中空通道，中空通道具有两个开口端，称为第一开口端41与第二开口端42(图1中，第二开口端42在第一开口端41的对侧，图1中未画出第二开口端)，第一开口端41用于燃料气体流入中空通路，设置在阳极层的第一侧面71，第二开口42端用于燃料气体流出中空通路，设置在阳极层的第二侧面72。

[0059]如图2所示，对该电池进行封装，包括利用第一阳极盖板51对阳极层的第一侧面71进行封装，利用第二阳极盖板52对阳极层的第二侧面72进行封装，利用第一阴极盖板61对第一阴极层的封装以及利用第二阴极盖板62对第二阴极层的封装。

[0060]本实施例中，阳极层采用Ni / YSZ复合材料多孔材料，简称Ni / YSZ，并且在中通道的内壁附着Cu，形成Cu-Ni / YSZ复合电极，燃料气体为氨气，并且沿着燃料气体的流动方向，Cu的含量逐渐减小。

[0061]首先，采用数值模拟的方法对不同铜分布下的温度场进行计算。计算基于有限单元法，采用全耦合的数值模型，计算过程与文献：Wang Y,Gu Y,Zhang H,Yang J,Wang J,Guan W,et al.Efficient and durable ammonia power g...

Abstract

The invention provides an anode material of a solid oxide fuel cell and a preparation method thereof. The fuel gas first undergoes reforming reaction inside the solid oxide fuel cell, and then diffuses to the anode for electrochemical reaction. The content of the material gradually decreases, and the catalytic reforming activity of the added material to the fuel gas is less than that of nickel. The internal reforming reaction rate distribution of the solid oxide fuel cell using the anode material is uniform, which is beneficial to improving the stability and service life of the cell.

Description

technical field [0001] The invention relates to the technical field of solid oxide fuel cells, in particular to an anode material of a solid oxide fuel cell and a preparation method thereof. Background technique [0002] Since the development of industrialization, global energy consumption has shown a rising trend. Environmental pollution and global climate change have aroused widespread concern. Governments around the world have focused on finding new clean energy and developing clean and efficient solutions for existing energy. Support, and fuel cells stand out among many solutions because of their clean and efficient advantages. [0003] Solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) is a clean and efficient all-solid-state energy conversion device that can directly convert chemical energy into electrical energy through electrochemical reactions. °C), it shows wide adaptability to various fuels such as methane, ammonia, alcohols, etc., becoming the third generation ...
