1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Understanding the properties of carbon supports is essential for optimizing the performance and durability of Pt-based catalysts in polymer electrolyte membrane fuel cells (PEMFCs). This review examines recent advances in the characterization and functional role of carbon supports, focusing on porosity, graphitization, and chemical modifications. Key methods used to assess the ordering of carbon phases and structural features are discussed, with attention to how these characteristics influence catalyst behavior. Particular emphasis is placed on the importance of fair comparison between Pt/C catalysts with different carbon supports, ensuring reliable performance assessments. The review then explores the interplay between graphitic and amorphous domains, highlighting how surface chemistry and chemical modifications can affect catalyst activity and stability. The impact of porosity and platinum nanoparticle locality is also examined, with special focus on how pore architecture can offer protection from ionomer-induced poisoning and inhibit nanoparticle coalescence during operation. Throughout, the review identifies challenges in current characterization techniques and underscores the need for a holistic understanding of support architecture. Finally, it outlines design principles for next-generation carbon supports that can better stabilize Pt nanoparticles and enhance the overall performance and durability of PEMFC cathodes.
