6.2 kW fuel cell
Hydrogen tank at 30 bar

The residential building in Brütten in the Swiss district of Winterthur follows increased ecological and energy standards and was initiated by “Umwelt Arena AG”. The house requires no external energy supply, neither thermal nor electrical. All electrical and thermal energy is drawn from the sun and distributed throughout the year by various forms of storage (short-term and seasonal storage) in the building. The solar energy is converted into electricity via the solar cells and temporarily stored in daily or medium-term battery storage units for use in the building. For long-term storage, a new type of conversion from electricity to hydrogen is used. The hydrogen is temporarily stored and converted into electrical and thermal energy via a fuel cell when needed.

In this project, Proton Motor is responsible for converting the stored hydrogen back into electricity and feeding the electrical energy into the DC circuit of the house. For this purpose, the PM Module S8 fuel cell module is integrated with a DC/DC converter in a 19-inch cabinet. Furthermore, Proton Motor’s scope of delivery includes a heat exchanger that makes it possible to use the thermal energy generated during the process to heat the house’s hot water.
