Activity in electrolytes

ECN Holland works on both the SOFC and PEMFC. For the PEMFC its web site asserts the imminence of breakthroughs in materials development. ECN is active in electrolyte development, electrode and catalyst development, and stack development. No description is given of the detail design features. 

Equation (2.70) contains the ions activity an+ and aA- instead of the concentration of the ions and [2,20]. Once the activity coefficients are defined, the dissociation constant remains the same and does not depend on the total concentration of the electrolyte. Table 2.6 summarizes the methods used to define the activities in electrolytes.
