Background
● What is a hydrogen fuel cell?
● How does a fuel cell work?
● What is the membranes function in a fuel cell?
Proton Exchange Membrane
● Chemical Energy = Electrical Energy
● H2 2H+ + 2e-
● Protons permeate through
● Electrons travel along load circuit
Question/ Hypothesis
● How does temperature affect the ion transfer across fuel cell membranes?
● Lower at 32-40 degrees
● Higher at temperatures 90-95 degrees
Procedure
● Independent Variable: Temperature
● Dependent Variable: Ion Transfer (Conductance in µS/cm)
● Controls: Membrane, Solutions
