    Abstract: The present invention provides a membrane-less fuel cell that comprises a microfluidic channel system at an interface (5) between two wafers (21, 22) with a fuel gas channel (9) and an oxidiser gas channel (7) overlapping each other in order to make a laminar fuel gas flow in the fuel gas channel (9) to meet a laminar oxidiser fuel gas flow in the oxidiser gas channel (7) in a fuel cell cavity between two parallel electrodes (10, 11), whereby ions are exchanged by diffusion between said flows via a diffusion zone (8). Each of the fuel gas channel (9) and the oxidiser gas channel (7) comprises serially connected sub-cells (1, 2, 3), thereby forming an array of sub-cell cavities for ion exchange. The efficiency of the fuel cell is improved by having a sub-cell configuration that differs from one sub-cell to another. Further the fuel cell can easily be scaled up with maintained efficiency by having a plurality of gas channels forming a matrix of sub-cell cavities.

    Abstract translation: 本发明提供了一种无膜燃料电池，其包括在具有燃料气体通道（9）的两个晶片（21,22）和氧化剂气体通道（7）之间的界面处的界面（5）处的微流体通道系统， 以使得燃料气体通道（9）中的层状燃料气体流动以满足在两个平行电极（10,11）之间的燃料电池腔中的氧化剂气体通道（7）中的层状氧化剂燃料气体流，其中离子为 通过扩散区（8）在所述流之间通过扩散交换。 燃料气体通道（9）和氧化剂气体通道（7）中的每一个包括串联连接的子电池（1,2,3），从而形成用于离子交换的子电池腔阵列。 通过具有不同于一个子单元的子单元配置来提高燃料电池的效率。 此外，燃料电池可以通过具有形成子电池腔矩阵的多个气体通道而容易地按照维持的效率放大。
