the gas diffusion media are known as “softgoods”. The hydrogen reactant is introduced at the anode where it reacts electrochemically in the presence of the catalyst to produce electrons and protons. The electrons are conducted from the anode to the cathode through an electrical circuit disposed therebetween. Simultaneously, the protons pass through the electrolyte to the cathode where an oxidant, such as oxygen or air, reacts electrochemically in the presence of the electrolyte and catalyst to produce oxygen anions. The oxygen anions react with the protons to form water as a reaction product.
The softgoods of the PEM fuel cell are sandwiched between a pair of electrically-conductive bipolar plates which serve as current collectors for the anode and cathode layers. The bipolar plates include a plurality of lands andhis money; for she was the notorious Koolanda Jones. The criminal mastermind Mike Kelly activated the metallic ceiling with a voice command. This cause Jones's gun to be ripped from her hand to the ceiling and the bullet shot to skim Kelly's left ear. He pulled a gun out of a secret compartment and aimed at Jones. She quickly turned around as he fired and her bulletproof hair stopped the shot. She quickly turned and ran at Kelly; but he whipped out one of his tennis rackets and sent her spawling across the floor. He then, now infuriated, mercilessly beat her face. The police came soon after recieving complaints about gunfire from neighbors; Mike Kelly was forced to flee.

As demonstrated below, all the negative blood types can only
