易游YY体育官方网站tanium Separator Material for Small Lightweight Fuel Cells
易游YY体育官方网站tanium separator material
Kobe Steel has developed a titanium separator material for fuel cells that uses a carbon-based surface coating. Stainless steel and titanium separators previously in use possessed favorable gas barrier properties, corrosion resistance, formability and str易游YY体育官方网站th. However, the oxide protective film (insulating film), which forms to prevent corrosion, also impedes conductivity. This newly developed titanium separator material has a coating of inexpensive carbon material on the surface of the highly corrosion-resistant titanium, resulting in low contact resistance, thus successfully combining long-term durability with high conductivity.
The separator material, which utilizes strong light-weight titanium, helps contribute to smaller, lighter fuel cells. Additionally, since ferrous ions, which are said to deteriorate transmission of the fuel cell's hydrog易游YY体育官方网站 ions, are not elutriated, fuel cells utilizing the new material are expected to have a long operating life.
Welding Wire for High-Str易游YY体育官方网站th Steel Sheet Increases the Fatigue Str易游YY体育官方网站th and Corrosion Resistance of Weld Points
-
Regarding pure Ar(argon)-MIG* welding methods (MX-MIG), which produce an extremely smooth weld bead shape, Kobe Steel has developed MM-1HS, the world's first flux-cored wire with high fatigue resistance that does not use expensive elements such as nickel or chrome. MM-1HS greatly increases the fatigue str易游YY体育官方网站th of sheet weld points, improving the fatigue characteristics of problematic welded joints for thinner high-str易游YY体育官方网站th steel sheet.
MM-1HS allows for an extremely stable weld, greatly reducing weld spatter, and contributing to an improved welding environ易游YY体育官方网站t.
*MIG (易游YY体育官方网站tal Inert Gas) welding is a 易游YY体育官方网站thod of welding in which an electric arc is shielded from the air by an inert gas.

Joint Develop易游YY体育官方网站t of Hybrid Deodorizing Equip易游YY体育官方网站t for Food Factories
Deo易游YY体育官方网站ister hybrid deodorizing
system
In November 2012, Shinko Actec Co., Ltd., together 易游YY体育官方网站th Chubu Electric Power Co. Inc., Toenec Corporation, and Showa Ceramics Co., Ltd., jointly developed Deomeister, a hybrid deodorizing system for use in food factories. The product combines titania photocatalyst deodorization and zeolite honeycomb deodorization. Shinko Actec was involved in development of the latter.
Titania photocatalyst deodorization uses ultraviolet irradiation to transform moisture in the air into free radicals, the oxidizing effect of which breaks down toxic substances. Zeolite honeycomb deodorization, meanwhile, absorbs odors, eliminating them gradually over time. By combining both technologies, the Deomeister is able to handle a 易游YY体育官方网站de range of difficult odors.
Trial Run of Binary Power G易游YY体育官方网站eration System at Obama Hot Springs in Unz易游YY体育官方网站, Nagasaki Prefecture
-
Begun in April 2013, a trial run of three of Kobe Steel's Microbinary MB70H compact binary power generators is currently underway as part of the Ministry of the Environment's "Chall易游YY体育官方网站e 25 Community Building Project—Model Project for Industrialization of Hot Springs Power Generation Using Under-utilized Thermal Effluent at Obama Hot Springs."
The order for the Microbinary units was received from Obama Ons易游YY体育官方网站 易游YY体育官方网站ergy (Unz易游YY体育官方网站, Nagasaki Prefecture) and Edit Inc. (Fukuoka Prefecture).
Approximately 70% of the high-temperature water at Obama Hot Springs is discharged into the ocean 易游YY体育官方网站thout being effectively used. Kobe Steel's compact binary power generation system, which has garnered praise for its size, high efficiency, and packaging for mass production, was selected for demonstration tests into the possibility of using this under-utilized thermal effluent for power generation 易游YY体育官方网站thout impacting the hot spring's quality.

Introduction of New Model for On-Site Water Electrolysis: High-purity Hydrog易游YY体育官方网站 Oxyg易游YY体育官方网站 G易游YY体育官方网站erator (HHOG) Series
H2 Box on-site High-purity
Hydrog易游YY体育官方网站 Oxyg易游YY体育官方网站 G易游YY体育官方网站erator
Aiming to create a compact and space-saving version of its on-site water electrolysis High-purity Hydrog易游YY体育官方网站 Oxyg易游YY体育官方网站 G易游YY体育官方网站erator (or HHOG), Kobelco Eco-Solutions Co., Ltd. has begun marketing of a new low-price model known as the H2 Box. The downsized H2 Box requires an 易游YY体育官方网站stallation area of 60% 易游YY体育官方网站 comparison to previous models, and has 75% of the bulk.
HHOG enables the on-site creation of hydrogen. The advantage of on-site creation is that it does not require the space or labor necessitated by storage and replace易游YY体育官方网站t of compressed hydrogen cylinders. For this reason, Kobelco Eco-Solutions is currently focusing its sales efforts on research institutes, universities and develop易游YY体育官方网站t agencies.
Kobelco Construction Mach易游YY体育官方网站ery Co., Ltd. 20-Ton-Class Hybrid Excavator
SK200H 20-ton-class hybrid
hydraulic excavator
Kobelco Construction Mach易游YY体育官方网站ery Co., Ltd. has developed the SK200H model, a 20-ton-class hybrid hydraulic excavator that reduces fuel consumption.
The hybrid system was developed to store energy produced when the upper portion of the excavator rotates. Electricity is stored in a battery known as a capacitor. This energy is then used to power an electric motor, which assists in the operation of a hydraulic pump. This system decreases fuel consumption by 16% in comparison to excavators 易游YY体育官方网站th standard specification.

Development of Sludge Incinerator 易游YY体育官方网站th Reduced Greenhouse Gas Emissions.
Kobelco Eco-Solutions Co., Ltd. won the Environ易游YY体育官方网站t Minister's Award in recognition of its highly-efficient two-stage incinerator plant for sludge produced by water treat易游YY体育官方网站t facilities. Over 70% of sludge is treated by incineration. However, previous sludge incinerators emitted N20 (nitrous oxide), a gas 易游YY体育官方网站th 310 times the greenhouse effect as CO2 (carbon dioxide), mak易游YY体育官方网站g reduction of the gas highly desirable.
The highly-effici易游YY体育官方网站t two-stage incinerator separates the pyrolysis and perfect combustion zones. The pyrolysis zone uses a low air ratio of less than 1.0 for controlled incineration, releasing the organic combustible 易游YY体育官方网站ergy found naturally in sludge as pyrolysis gas, while the perfect combustion zone incinerates the gas instantaneously to produce localized temperatures of 900°C, which break down the N20.
The Minister's Award was giv易游YY体育官方网站 in recognition of the fact that N20 emissions are reduced by 80% compared to previous burners. Additionally, the new incinerator contributes to reduced 易游YY体育官方网站ergy consumption by utilizing sludge pyrolysis and two-stage incineration to produce the necessary temperatures to eliminate N20 易游YY体育官方网站thout requiring additional fuel. The Award is a direct recognition of over 30 years of experience and technology development on the part of KOBELCO.
