A specific cross-linker, an alkaline metal bis(styrenesulfonyl)imide monomer, is used in the synthesis of single ionic conductive copolymers that are non-fluorinated and non-PEO based. Such copolymers meet the security and costs requirements to be used as solid polymers electrolytes (SPE). They are promising alternatives to standard liquid electrolytes in alkaline metal-ion batteries because of their improved security and inflammability properties. The copolymers described are either polyvinylsulfonates or acrylate vinylsulfonate block-copolymers. Preferred acrylate monomers are methacrylates and preferred vinylsulfonates are styrene sulfonates. The copolymer is prepared by radical polymerization of the vinyl sulfonate and the cross-linker and optionally the acrylate, in particular radical photopolymerization using a functionalized bis(acyl)phosphane oxide (BAPO) as photoinitiator. Also described is the use of such copolymer as solid polymer electrolyte in a lithium ion battery.

The present invention provides a method of operating a PEM fuel cell comprising an anode feed circuit and a cathode feed circuit for feeding of an anode side (14) with a reactant gas and for feeding a cathode side (16) with a cathode gas. Said method adapted for shutting down and for starting of an electricity generating operation of the fuel system, in the shut-down mode comprises the steps of : decreasing the supply of reactant gas and cathode gas in response of a shut-down signal, monitoring an output voltage of at least one cell of a fuel cell stack (12), monitoring the reactant gas pressure and the cathode gas pressure, electrically shunting of the at least one fuel cell in response of the output voltage reaching a predefined voltage level, at least reducing the pressure of the anode side (14) to a predefined pressure level by means of at least one pump (16, 18), and filling and/or flushing of at least the anode side (14) with an inert gas.
The method for limiting the output voltage of a PEM fuel cell system operating in, or near, zero load conditions, in such a way as to minimize degradation of performance over time, comprises : supplying a hydrogen stream to the anode of said fuel cell; supplying an oxygen stream to the cathode of said fuel cell; monitoring an output voltage of the fuel cell; monitoring a hydrogen pressure in the fuel cell; monitoring an oxygen pressure in the fuel cell; limiting the hydrogen stream and the oxygen stream while actuating controllable recirculating pumps for the hydrogen and the oxygen in such a way as to bring and maintain the hydrogen and oxygen pressures below 1 bar absolute while maintaining said hydrogen pressure between 70 and 130 % of said oxygen pressure, so that the output voltage remains below.90 volts.
A specific cross-linker, an alkaline metal bis(styrenesulfonyl)imide monomer, is used in the synthesis of single ionic conductive copolymers that are non- fluorinated and non-PEO based. Such copolymers meet the security and costs requirements to be used as solid polymers electrolytes (SPE). They are promising alternatives to standard liquid electrolytes in alkaline metal-ion batteries because of their improved security and inflammability properties. The copolymers described are either polyvinylsulfonates or acrylate vinylsulfonate block-copolymers. Preferred acrylate monomers are methacrylates and preferred vinylsulfonates are styrene sulfonates. The copolymer is prepared by radical polymerization of the vinyl sulfonate and the cross-linker and optionally the acrylate, in particular radical photopolymerization using a functionalized bis(acyl)phosphane oxide (BAPO) as photoinitiator. Also described is the use of such copolymer as solid polymer electrolyte in a lithium ion battery. (see formula I)
