Anode-Supported Micro-SOFC Stacks Operated under Single-Chamber Conditions

Abstract A single-chamber ICD is a standard method for primary SCD prophylaxis. In patients with chronic atrial fibrillation it does not contribute to the regularization of heart rate, which is crucial for proper treatment. Moreover, to avoid the deleterious effect of right ventricular pacing only minority of the patients with single chamber ICD get the appropriate, recommended dose of beta-blockers. The aim of our study was to assess the efficacy of direct His-bundle pacing in a population of patients with congestive heart failure and chronic atrial fibrillation using upgrade from single chamber to dual-chamber ICD and atrial channel to perform the His-bundle pacing Methods The study population included 39 patients (37 men, 2 women) aged 67.2±9.3 years, with CHF and chronic AF implanted primarily with single chamber ICD with established pharmacotherapy and stable clinical status. Results The echocardiography measurements at baseline and during follow-up were presented in the table: During short period (3–6 months) of follow-up the mean values of EF and LV dimensions significantly improved. This was also accompanied by functional status improvement. Conclusions His-bundle-based pacing in CHF-chronic AF patients contributes to significant echocardiographic and clinical improvement. Standard single-chamber ICD implantation in CHF-chronic AF patients yields only SCD prevention without influence on remodeling process. The physiological pacing contributes to better pharmacotherapy.

AbstractChanges are needed to improve the efficiency and lower the CO2 emissions of traditional coal-fired power generation, which is the main source of global CO2 emissions. The integrated gasification fuel cell (IGFC) process, which combines coal gasification and high-temperature fuel cells, was proposed in 2017 to improve the efficiency of coal-based power generation and reduce CO2 emissions. Supported by the National Key R&D Program of China, the IGFC for near-zero CO2 emissions program was enacted with the goal of achieving near-zero CO2 emissions based on (1) catalytic combustion of the flue gas from solid oxide fuel cell (SOFC) stacks and (2) CO2 conversion using solid oxide electrolysis cells (SOECs). In this work, we investigated a kW-level catalytic combustion burner and SOEC stack, evaluated the electrochemical performance of the SOEC stack in H2O electrolysis and H2O/CO2 co-electrolysis, and established a multi-scale and multi-physical coupling simulation model of SOFCs and SOECs. The process developed in this work paves the way for the demonstration and deployment of IGFC technology in the future.
