The role of the fuel cell in a smart house

Abstract

Reducing the amount of CO₂ emissions in residential sector is urgent and critical issue, and to achieve this objective, increasing the popularity of the house that emits very little CO₂ is the key factor. Smart House composing of the energy saving technologies, fuel cell system and photovoltaic generation system satisfies this precondition of being poplar, such as that it is comfortable to live, the utility expenses are low, it can offset CO₂ emissions, the capacity of photovoltaic generation system can be comparatively small, and the appearance of the house isn’t restricted.

By the great earthquake on March 11, 2011, the needs of the smart house which can respond to the shortage of electric power supplies or a blackout have grown. For this reason, the “Green First Hybrid” with the system which combined the photovoltaic, the fuel cell, and the storage battery was made. In a “Green First Hybrid”, television and a refrigerator can be used also at the time of a blackout. Furthermore, bathing is also possible and the life near usually is possible. As for this, power generation of a fuel cell contributes greatly.

From now on, the smart house using hydrogen can also expect development.
