Panasonic launches 5kW fuel cell system for commercial applications – pv magazine International

The system has dimensions of 834 × 417 × 1766 mm and weighs 205 kg including the design panel. It achieves an electrical efficiency of 56% and can be connected to a hot water accumulator.

Japanese electronics maker Panasonic has launched a 5kW pure hydrogen fuel cell generator for commercial applications. It has already installed the fuel cell in several pilot projects in Japan.

Dubbed H2 Kibou, the fuel cell system works with pure hydrogen at a density of over 99.97% and achieves an electrical efficiency of 56%. “The higher electrical efficiency leads to the reduction in hydrogen consumption, thereby helping to reduce the total cost of operation,” the manufacturer said in a statement.

The system has dimensions of 834 × 417 × 1766 mm and weighs 205 kg including the design panel. “The power output can be increased according to demand by connecting and controlling multiple generator sets,” the company said. “In addition, by taking advantage of its light and compact housing, this generator can be flexibly adapted to various installation conditions, including on the roof and in tight spaces. “

The company also explained that using a simple PC application, it is possible to group up to ten units for a total capacity of 50 kW, and that these units can be combined further to create an installation of the size of a MW. “By connecting a hot water storage unit (recommended product) with the product, the heat generated by the fuel cell can be converted into hot water for use,” he also pointed out. “The generator has achieved a total energy efficiency of 95%, including heat recovery, allowing efficient use of energy without waste. “

The new product can be used with an operating temperature between -10 and 40 degrees Celsius, at altitudes not exceeding 500m. During power outages, it is able to generate electricity and use up to 2.5 kW of its capacity for at least 120 hours. “The product can be started in about a minute, which is useful for responding to peak cutoff control when rapid response from the generators is required,” said Panasonic.

The device was used by the Japanese conglomerate in a pilot plant for hydrogen combined with photovoltaics and storage that it built at its fuel cell plant in Kusatsu, Shiga Prefecture, central Japan. .

“With this demonstration, Panasonic will build up its know-how and establish a track record in energy management, including the operation of pure hydrogen fuel cell generators, and will aim to commercialize the RE100 solution, which uses energy produced internally from renewable sources to provide 100% of the electricity needed for commercial activities, ”the company said at the time.
