Oxygen Reduction Reaction on Cathode Catalysts
Oxygen Reduction Reaction on CathodeCatalystsThe development of clean energy has become an important global issue in recent years, and the fuel cells have been considered as one of the most promising candidates to replace traditional fossil fuels due to their high energy efficiency and low environmental impact. The cathode catalyst, which plays a key role in the oxygen reduction reaction (ORR), is one of the most important components of fuel cells. In this article, we will discuss the recent progress in the development of cathode catalysts for ORR.Overview of Oxygen Reduction ReactionORR is a crucial reaction in fuel cells, as it determines the electricity production efficiency and the durability of the fuel cells. The overall reaction equation of ORR is:O2 + 4e- + 4H+ → 2H2OAs shown in the equation, the ORR involves the reduction of the oxygen molecule (O2) into water (H2O) with the consumption of four electrons and four protons. The ORR process is kinetically slow, and requires a catalyst to reduce the activation energy barrier and increase the reaction rate.Cathode Catalysts for ORRThe cathode catalysts for ORR should possess high activity, selectivity, and durability. However, the currently used catalysts, such as platinum (Pt), suffer from several problems, including high cost, scarcity, and instability under harsh working conditions. Therefore, developing alternative catalysts with low cost, high activity, and excellent durability is urgently needed for the commercialization of fuel cells.One of the most promising alternatives for Pt-based catalysts is non-precious metal catalysts, which are usually composed of transition metals, such as Fe, Ni, Co, and their oxides. These catalysts have several advantages, such as low cost, high stability, andabundant resources. However, the overall catalytic activity and durability of these catalysts are still far from the requirements of commercial fuel cells.Another promising approach is to use composite catalysts, which combine the advantages of different types of catalysts and exhibit superior performance. For example, Pt-based composite catalysts, such as Pt-based alloys, PtCo/C, and PtNi/C, have been reported to show enhanced ORR activity and durability compared with single-component catalysts. In addition, nanostructured catalysts, such as core-shell nanoparticles and nanowires, have emerged as a new class of ORR catalysts with high surface area, low resistant, and improved mass transport.ConclusionIn summary, ORR is a crucial reaction in fuel cells, and the development of high-performance cathode catalysts for ORR is critical for the commercialization of fuel cells. Non-precious metal catalysts and composite catalysts are considered to be promising alternatives to traditional Pt-based catalysts. However, further research is still needed to optimize the catalyst design, improve the activity and durability, and reduce the cost of the fuel cells.。

include mainly compilation errors (for example misplaced parentheses) and some run-time errors (for example infinite loops). 2. Deep errors - those that can not be diagnosed directly from their symptoms. These are mainly logic errors. We will be concentrating on deep errors since they are the most difficult to find. Deep errors occur in programs that compile, run and terminate successfully but give incorrect output. These programs are not faulty in themselves alter all they solve some programming problem. They are faulty because they give results which differ from those that the programmer intended. In these cases diagnosis requires knowledge not only of how the program behaves but also of how the user intended it to behave.
• Lexical errors • Syntactic errors • Semantic errors • Teleological errors • Conceptual errors We will refer to lexical and syntactic errors as compilation errors and the other types as runtime errors. Teleological and conceptual errors will be referred to as logic errors. Errors were classified across a different dimension by Harandi (1983). He defined two types of error 1. Shallow errors - those that can be diagnosed directly from their symptoms. These
1 Introduction
Last year we introduced our thoughts on an interactive system to help novices debug their Pascal programs (Smith and Webb 1991). This system, called Bradman, is still in the implementation stage. Here we present on how our ideas have since developed. Novices generally find learning their first programming language a difficult and frustrating business. They lack the experience to find errors in their programs and often need to seek help from more experienced programmers. A computer- based debugging assistant, available twenty four hours a day, would be of great benefit to people in this situation. Last year we described in broad outline how Bradman might operate. This year we would like to discuss more fully how Bradman is to model the user’s program in order to find bugs.
To find the error the tutor must first gather information about the program. There are several sources of information that he might utilise
• The program code • A program specification • Examples of faulty program behaviour • His own knowledge of programming • Consultation with the user It is necessary for the tutor to use this information to determine why the implemented program does not behave as the user expects.
2.2 Modelling the Program It would seem natural, therefore, that an automated debugging system should compare two models of the program. These would be an intentions model (reflecting what the program is supposed to do) and an implementation model (reflecting what the program actually does). This is not a new concept. PROUST (Johnson, Soloway 1984), Laura (Adam, Laurent 1980) and Pudsy (Lukey 1980) all operate in this way. These systems are given information regarding the user’s intention in the form of a program specification. This specification must be given to the system before diagnosis of an individual program can commence. Bradman differs from these systems by constructing a model of the user’s intentions while diagnosis is actually taking place without reference to a predefined program specifica; Webb, G.I.

2.1 Diagnosing Deep Errors When programmers with some experience find bugs in their programs they draw on their experience of programming to help them conduct a search for the error. They can also make use of tools which provide a more friendly environment for this search. These tools usually perform a trace of the program execution which enables the programmer to step through his program examining the values of certain variables at critical points etc. These tools make no attempt to diagnose the error. The user retains the responsibility to hypothesize about the possible causes of the error and, once the cause has been found, to modify his code appropriately. This requires programming experie nce thus making these tools inappropriate for novices.
