is the use of hydrogen as a fuel source becomes more prolific, alternatives o classical gas compression are needed. Water splitting from humid air is an ttractive method whereby the hydrogen can be produced on-demand. To do his, a microporous spherical catalyst pellet impregnated with Ru lanoparticles is proposed for on demand reforming. The porous pellet is 80 1m thick and the water is known to diffuse in with Dwc=5.24109m2/s and ecompose within the pellet with first order reaction kinetics with a rate onstant of krxn=9.01s1. Water adsorbs onto the catalyst in accordance with lenry's law, cw=Hpw,H=10mol/LkPa. Assume the air is 45% relative umidity at 30C and atmospheric pressure. a) What is the concentration profile of water within the pellet at steady state? Hints: list your domain, boundary conditions, GMB with assumptions, then evaluate symbolically, then plug in numbers. b) How far can I travel in a day if I have a 1L packed bed reactor ( 40% void fraction)? Assume I drive the Toyota Mirai LE and the H2 generator runs 24 hours per day
