This invention relates to a transportable electricity generation unit ( 30 ) suitable to supply electric power to an external load ( 51 ). Said electricity generation unit ( 30 ) comprises: a photovoltaic generation unit ( 1 ) and/or an aerogenerator generating a first electric power (P 1 ), a water electrolyzer ( 4 ) connected to said photovoltaic generation unit ( 1 ) and/or aerogenerator, said electrolyzer being capable of producing hydrogen by electrolysis of water; a tank ( 3 ) to store the hydrogen deriving from said electrolysis of water; a fuel cell unit ( 2 ) fed with the hydrogen produced by said electrolyzer ( 4 ) or stored in said tank ( 3 ), said fuel cell ( 2 ) generating a second electric power (P 2 ), a battery accumulator unit ( 5 ); an electronic power control device ( 8 ) comprising means for controlling the flow of said first electric power (P 1 ) and said second and third electric power (P 2 , P 3 ) to said external load ( 51 ), controlling the flow of said first electric power (P 1 ) to said water electrolyzer ( 4 ), and for controlling production and storage of hydrogen. |
