An apparatus and method provide for automated converting of a web of a thin patterned catalyst-coated membrane to separate membrane sheets for fuel cell assembly. By selecting the passivation layer to have a higher bandgap than the HBT components, minority carriers are contained within the HBT by the passivation layer. The first electrical connector defines a slot for receiving an edge of a first printed circuit board. A first collector of a first bipolar junction transistor of the device structure may be formed at a first spacing from the first sidewall. The said copolymers show an excellent balance of impact and optical properties which is retained even after visbreaking. Another system simultaneously irradiates opposite sides of the workpiece to form a set of laterally offset laser shock peened surfaces.
