Abstract
A vehicle (10) comprises a hydrogen fuel ceil (12) and a hydrogen storage tank (14). The storage tank includes an intake valve for connecting with an external hydrogen source (26) to Fill the tank (14), A hydrogen supply line (16) is provided for supplying hydrogen to the fuel cell from the storage tank (14). Heat transfer means (14, 22) transfers heat from the storage tank (14) to the fuel cell (12). Heat expelled by the storage tank during filling thereof is captured and transferred to the fuel cell (12).
Claims2
A fuelling system comprising a vehicle comprising a hydrogen fuel cell, a hydrogen storage tank having an intake valve for connecting with an external hydrogen source to fill the tank, a hydrogen supply line for supplying hydrogen to the fuel cell from the storage tank, and a heat transfer mechanism to transfer heat from the storage tank to the fuel cell, wherein heat expelled by the storage tank during filling thereof is transferred to the fuel cell, the system further comprising an external hydrogen source for connecting to the intake valve, wherein control of the filling is dependent upon a timer which can be set to activate the filling at a predetermined time, wherein the heat transfer mechanism comprises a first thermal envelope associated with the hydrogen fuel cell and a second thermal envelope associated with the hydrogen storage tank, the first and second thermal envelopes fluidically connected together such that a fluid flows between the first and second thermal envelopes so as to transfer said heat between the storage tank to the fuel cell.
