Claim:
1. A personal protection arrangement in a vehicle, the personal protection arrangement comprising: a gas generator for fluid communication with a reservoir of the personal protection arrangement; and a control unit arranged to activate the gas generator upon fulfillment of at least one predetermined criterion selected from a crash or impending crash such that a gas is released by the gas generator into the reservoir and the pressure in the reservoir is increased; wherein the gas generator includes at least one electrochemical cell, the at least one electrochemical cell arranged to generate the gas when an electrical status of the at least one electrochemical cell is changed from a charged state in which energy for generation of the gas is stored in an electrochemically active material of the at least one electrochemical cell to a discharged state in which the energy for generation of gas is dissipated to generate the gas through chemical reactions which decompose the electrochemically active material by a state-changing action, the at least one electrochemical cell having a lesser electrical charge in the discharged state than in the charged state.
