This new technology enables efficient power generation from a small cell volume. Thus, the use of this technology can make it possible to develop fuel cells that have almost the same volume but a longer continuous.

Because fuel cells use energy produced by the chemical reaction between hydrogen and oxygen, they have a small impact on the global environment. Also, fuel cells are expected to become the next-generation power generating devices because of their high generating efficiency that comes from converting chemical energy directly into electrical energy. In particular, DMFC have a simple structure in which power is generated through a chemical reaction between methanol supplied directly to the power generation part and oxygen in the air, making them suitable for miniaturization.

In the future, through continuing to pursue the development of this elemental technology, cell volume can be further miniaturized, and the creation of cells with the same volume but a longer lifespan than the currently mainstream lithium-ion batteries can be achieved.
