- D1.1 - Project shared workspace implemented and operational - Confidential
To fulfil two fundamental internal project communication requirements: i) efficient exchange between partners of information about CRESCENDO project ii) decentralised and secured archiving of the documents generated, one independent and secured web-based communication tool: Project Shared Workplace – PSW has been implemented with a restricted access for project partners only. Among all the functionalities installed on this PSW, for now partners have a total access to the following tools: Document sharing and archiving ; Meeting organization ; General project communication ; Online working document ;  Project management.
The PSW maintenance is therefore an on-going activity that will go along with the project lifetime

- D2.1 - Cell and system requirements and cell testing protocols
In this deliverable report the technical specifications for the CRESCENDO single cell components are presented. The specifications are based on the automotive requirements and operating conditions. In addition standard testing protocols and sensitivity tests are defined for the purpose of fair comparison between partners, while integrating European harmonised protocols where relevant.

- D3.1 - Site Density and Turnover Frequency of Selected Benchmark Catalysts
This deliverable report describes the benchmarking of four non-platinum group metal (non-PGM) containing catalysts, consisting of key performance metrics, such as electrocatalytic mass activity (MA), selectivity, site density (SD) and catalytic turnover frequency (TOF). SD and TOF were evaluated using in situ nitrate reduction and ex situ low temperature CO chemisorption in combination with rotating ring disk electrode (RRDE) measurements. The iron coordination environment was determined by 57Fe Mössbauer spectroscopy. Surface area and pore volume were determined from nitrogen adsorption isotherms. Electrochemical measurements were performed with a RRDE to determine the kinetic current and the selectivity of the catalysts to the oxygen reduction reaction (ORR). The properties of these benchmark catalysts will be used as a baseline to guide needs to increase the SD or TOF to reach the activity targets of the project, and to better assess the activity improvements realised with the new non-PGM catalysts prepared in CRESCENDO.

- D4.1 - Ex situ AST peroxide protocol definition and its application to selected benchmark catalysts
In this deliverable report a novel protocol is established to investigate the effect of H2O2 on the activity for O2 reduction of Fe-N-C catalysts. The novel protocol involves a continuous addition of a peroxide solution with a peristaltic pump. A well-known Fe-N-C catalyst was selected, for which the effect of H2O2 had previously been investigated by adding peroxide instantaneously. This former protocol may however have led to different effects than when peroxide is added continuously, the latter case better reproducing the conditions occurring in an operating PEM fuel cell. Several parameters of this peroxide-accelerated stress test were investigated, such as the rate of addition of peroxide and the pH. The results show that, for a same cumulative amount of peroxide per mass of Fe-N-C catalyst, a similar decrease in ORR activity is observed for the investigated Fe-N-C catalyst when applying either the novel (continuous addition of peroxide) or the former protocol (instantaneous addition of peroxide). The rate at which peroxide is added with the pump plays only a minor role on the deactivation, in the range investigated so far. The pH of the solution in which the Fenton reaction takes place has a role, with more acidic pH leading to slightly less active catalyst than when deionized water is used.
The novel AST with peroxide proved reproducible and allows an easy control of the cumulative amount of peroxide added and also the rate at which it is added. This protocol will now be applied to other FeNC catalysts (benchmarking study) and also to novel catalysts prepared in CRESCENDO.

- D7.1 - Project Website - Confidential
The CRESCENDO project website is designed to fulfil project communication and dissemination needs for the benefit of the whole scientific community and the public through relevant information including:
− project overall objectives, partner & work packages information
− project activities: news, meetings
− project progress: technical publications, conference presentations, public domain reports
− project resources: links, related events …
− project contact information and newsletter subscription
All the partners will collectively participate in the dissemination objective of the website by providing up-to-date information

- D7.2 - Dissemination and knowledge management protocol - Confidential
This report presents the dissemination protocol for the CRESCENDO project, the procedure for “Open Access” to peer reviewed research articles, internal rules, information on support from the EU members and the strategy for Knowledge Management within the project.
