Description

(1) Technical field

[0001] The invention relates to a fuel cell, in particular to a silicon-based planar fuel cell group. The invention also relates to a method of making such a fuel cell. (2) Background technology

[0002] Fuel Cell (FC) is a power generation device that uses chemical energy to be directly converted into electrical energy. Compared with traditional power generation methods, fuel cells have low pollution, low noise, high energy density, and high energy conversion efficiency. The advantage is that it is a very future-looking clean energy, which can be applied in various fields such as portable electronic products, household power generation systems, transportation tools, military equipment, space industry, and large-scale power generation systems.

[0003] The operating principle of fuel cells varies slightly depending on the type. Taking Direct Methanol Fuel Cell (DMFC) as an example, methanol aqueous solution undergoes an oxidation reaction on the anode ca...
