摘要:
Disclosed is a hybrid-type power supplying apparatus which may use a fuel cell device as a main power supplier for a robot and a rechargeable battery as an auxiliary power supplier for the robot. In the hybrid-type power supplying apparatus, when the power consumption of the robot exceeds the selected amount of power generation of the fuel cell device, the loads of the rechargeable battery and the fuel cell stack can be managed in such a manner that power is supplied from the rechargeable battery to the robot as an auxiliary power for the robot supplementing the main power for the robot.

摘要:
A separation plate having a gas flow path is segmented for analyzing MEA performance without segmenting an electrode or a gas diffusion layer. In advance, a MEA is operated for a long time in a real stack environment using a typical separation plate which is not segmented, and then the segmented separation plate for analyzing MEA performance is mounted to the MEA.

Disclosed is a polybenzimidazole based polymer, which can be used at high temperature under no-humidification conditions for preparing a fuel cell, in particular, a fuel cell membrane instead of the existing Nafion type perfluorosulfonated polymers, with which it is easy to increase a doping level, and also, which exhibits an excellent mechanical strength, further, which is inexpensive. Further, disclosed is a method for preparing the polybenzimidazole based polymer.
摘要:
The present invention, by coating the polymer electrolyte membranes for fuel cells with inorganic thin films via a PECVD method or a reactive sputtering method, reduces the methanol crossover sizably without seriously reducing the ionic conductivity of polymer electrolyte membranes, thereby, when applied to fuel cells, realizes a high performance of fuel cells. A surface of membrane can be coated with inorganic thin films made of inorganic materials, which are for example silicone oxide, titanium oxide, etc., so as to make composite polymer electrolyte membrane. For coating, plasma enhanced chemical vapor deposition method or reactive method can be used.
摘要:
Disclosed is a catalyst for a partial oxidation reforming reaction of fuel in the form of disk having through-hole. In addition, according to the invention, there is provided a fuel reforming apparatus and method using the catalyst. The catalyst for a partial oxidation reforming reaction of fuel according to the invention makes it possible to progress the partial oxidation reforming reaction of fuel smoothly, to improve the efficiency when reforming the fuel and to simplify the fuel reforming reactor. According to the fuel reforming apparatus and method, since the heat of reaction is efficiently controlled and used, a simple on-off operation, reduction of starting time and a stable operational condition are accomplished, which are indispensably required for a fuel reforming system in fuel cells, such as household, portable and car fuel cells.
