Abstract
A microwatt fuel cell stack that demonstrates a wide range temperature tolerance, low reactant cross-over and leakage, low internal leakage current, and/or effective water transport is disclosed. Both Hand Omay be supplied directly to the fuel cell stack (i.e., dead-ended). One-piece gas diffusion electrodes (GDEs) may serve as both the active electrode and manifold port. Water removal may be accomplished by permeation through the membrane to 'fins' exposed by notches in the bipolar plates and gaskets.
