Following the discussion of the criteria defining an effective catalyst, it is crucial to analyze the specific advantages of different groups of catalysts and understand the characteristics that make certain ones more valuable than others. This section will compare two primary catalyst groups used in fuel cells: Platinum Group Metals (PGM) and non-platinum Group Metals (non-PGM) catalysts, as all catalysts are built upon noble metal and non-noble metal catalysts. Therefore, examining these two groups could provide a better idea of which grouped catalysts are better, hence resulting in finding the more effective catalyst for society. This section will utilize the criteria established in the prior section to support the comparison between these groups, but with a significant emphasis on cost considerations in real-life applications. Throughout the comparison of the catalyst groups, data and statistics of individual catalysts will be referenced from research papers conducted by other researchers. This focused examination aims to provide a comprehensive understanding of the key catalysts within the PGM and non-PGM categories, considering their attributes and cost implications.
