Abstract
A hydrogen generating device, wherein a first substrate comprises a liquid container and a first gas container at a first side thereof, and the first substrate sequentially comprises a first, a second liquid diffusion area and a diverging channel area from the liquid container to the first gas container. The first and second liquid diffusion areas have multiple liquid diffusion structures respectively, and the diverging channel area has multiple diverging channels. A laminate covers the first side of the first substrate, and comprises a liquid feed inlet connected to the liquid container. A first side of a second substrate covers a second side of the first substrate, and comprises a second gas container and a gas reaction channel. A catalyst is disposed in the gas reaction channel, and a heater is disposed on the second side of the second substrate.
