Title: Tomohiro Hangai: Innovator in Fuel Cell Technology
Introduction
Tomohiro Hangai is a notable inventor based in Miyoshi, Japan. He has made significant contributions to the field of fuel cell technology, holding 2 patents that showcase his innovative approach to manufacturing methods.
Latest Patents
One of his latest patents is a manufacturing method for fuel cells. This method includes a laser application step and a bonding step. In the laser application step, a laser beam is applied to a carbon film of a separator that includes a metal plate. The carbon film covers the surface of the metal plate, and the laser beam removes the carbon film within the application range, exposing the metal plate. In the bonding step, the separator is bonded to a resin member, including at least part of the area where the metal plate is exposed. Another significant patent is the flash removing apparatus. This apparatus features a punch pin with a rotating mechanism. A flange is formed on the upper end portion of the cutting edge, and multiple grooves are created in the axis center direction towards the casting part from the flange. The inner portion of the punch pin is slidably inserted into an inner cover, and both the inner portion and the processing portion are moved by a spring cylinder to separate from each other. The spring cylinder compresses when the punch pin is near the casting part, allowing the flange to contact the flange portion of the casting part.
