Tear down of Toshiba's Dynario Fuel Cell Battery. Tech-on broke down the fuel cell battery, and they were surprised by the large number of components. It is equipped with many circuit components other then fuel cells such as ultra-small pump, valve, microcomputer, controller IC chip and controller board. We were also surprised by the sturdy chassis of the battery, which is made with metal plates and strong reinforcement materials.The Dynario has two power generating units, a cylindrical lithium-ion battery and two controller boards equipped with a power supply switch and an input-output terminal. The power generating unit is made by sandwiching generating cells between a lattice-shaped stainless steel plate and a resin chassis that works as a fuel feed plate and fixing them with rivets and caulking. Therefore, the cells cannot be taken out without breaking the unit.
The power generating unit is equipped with a fuel valve, a fuel pump and two controller IC chips for controlling them. The controller boards mounted with the power supply and the input-output terminal are used to control power from the power generating units and boot up the power generating units by using the lithium-ion battery.
