Hydrogen power source based on six alcaline Fuel Cells giving 150 w developed and produced by Hydrocell Ltd. Finland. Each fuel cell contains internal MH storage for hydrogen giving 50 Whrs/cell - total 300 Whrs capacity without external suply tank.
 

Converter ecpecialy designed to provide High efficiency 90..95% transforming
4.2 v at 40 A gived by the fuel cell stack, to 14 ,28 or 56 V . RISC controller embeded in converter also provides overloading protection of each cell,temperature & humidification controll, Air flow stochiometry, soft start function, output isolation when switched off, remote controll, auto shutdown when lack of hydrogen occures and LED indication for output voltage level.
