	・fuel cell There are kinds of fuel cells. However, we hereby refer to PEFC(abbreviation from Polymer Electrolyte Fuel Cell). This PEFC is suitable for less than 1kW power fuel cell. In comparison with battery, PEFC has advantage without long charging time.

・hydrogen generator

We show you hydrogen generator in way of "metal-chemical reaction".
Since hydrogen generated from this generator does not incude carbon monoxside, it is applicable for PEFC as above.

・hydrogen engine

Hydrogen combustion engine is being developed in competition with fuel cell. Using hydrogen engine instead of gasoline engine will reduce carbon dioxide emissions as using fuel cell in order to avoid global warming,
Fuel cell is surely ideal. However, it has very difficult problems such as lack of strength of membranes and high cost consuming precious metal of platinum.
At this stage, it seems that in some sense hydrogen engine is more earlier than fuel cell(PEFC) to be materialized for the market.
There are three types of hydrogen engine. Reciprocal engine. Rotary engine. Micro-gas turbine.
Our company succeeded to develop hydrogen combustion reciprocal engine to some extent. Our developed engine works well.
We can show you a motion picture of outboard vessel engine converted to use hydrogen as fuel.

Now, other than outboard engine, electric generator (reengineering of diesel engine) and lawnmower as hydrogen driven as well.
