This section will examine some essential characteristics that contribute to the efficiency of an electrocatalyst, establishing criteria for a promising electrocatalyst that will enhance the overall reaction efficiency of fuel cells from prior research and papers. This section's primary focus areas are the kinetics and durability of the catalyst. While the kinetics and other aspects of an electrocatalyst will significantly influence the performance of the catalyst, a balance must be made between better kinetics and durability and the associated cost implications. The better catalysts are more expensive within the fuel cells; however, an imbalance between the electricity generated and the amount of money invested in fuel cells will no longer make the utilization of fuel cells beneficial. Therefore, to create a better balance between cost and efficiency, this section guides how kinetics and durability are characterized in catalysts, as a more durable catalyst means less frequent replacements, thereby minimizing replacement costs. Similarly, a catalyst with better kinetics will increase the efficiency of the fuel cell, lowering the operational costs of the fuel cell. Thus, all aspects of the catalyst are intricately tied to the overall cost, knowing that only the most cost-effective catalyst will benefit our society.
