Using Equation 5.10, calculate the limiting current density for a fuel cell cathode running on air at STP. Assume only O2 and N2 and ignore the presence of water vapor. Assume that the diffusion layer is 500 μm thick and has a porosity of 40%.

step-by-step explanation:

their are no angles. sorry cant .

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
